Last Friday was my final field day in Kenya, but it had a little bit of everything: eating pineapple slices on a stick, sitting in traffic jams, a boat ride to Mbita, a broke-down matatu, and of course a successful installation with excited and helpful geography students of St. Williams Osodo Secondary School.

St. Williams, located in rural Osodo, was founded in 2002 by the local Catholic Church that sits on the school property. The school sits on a hilltop at 1280 m in this undulating region about 10 km from the coast of Lake Victoria, overlooking a dry landscape where cactus-like candelabra euphorbia and acacia trees dot the dusty relief. After Zach Dunn and I visited St. Williams on Monday to discuss TAHMO with Mr. Pius, the school principal and research enthusiast on community engagement in education, I had returned to install their weather station.

The geography students gathered around in the noontime heat and I set about explaining how a TAHMO weather station works. The students had all studied weather and climate topics in class, but usually only learn the concepts theoretically, such as the names of the instrumentation that measure different weather variables – sometimes without seeing photos of the devices, let alone handling the sensors. Mr. Pius and several of the geography teachers had operated manual weather stations with students in the past, taking daily measurements and keeping record books, but AWS (automatic weather stations) are uncommon in the Kenya secondary school arena. The TAHMO weather station we install measures all of the basic meteorology parameters (wind speed and direction, temperature, humidity, barometric pressure, rainfall, solar radiation) but does so with a novel compact device that has no moving parts. The anemometer we deploy is especially contrasted to the wind vanes and wind socks that Kenyan students are familiar with; it measures wind speed and direction by transmitting and receiving sonic signals, whose phase difference are proportional to the wind speed.

After answering a few questions about how the solar panel would charge the station on cloudy days (answer: solar panels can charge with direct and diffuse sunlight), we installed the station. Several students and teachers helped hold each component in place as we screwed the sensors onto a pole mounted in concrete and plugged our sensors into the data logger. Although some students were dubious about how water-proof the logger case was, I assured them not to worry and encouraged them to test its durability themselves by looking up whether the station was recording measurements after the first torrential rainfall of the season.

The long rains usually run from March to June in western Kenya, but this year they’ve been late in arriving. Osodo hasn’t seen rainfall in months, and the schools administration is eagerly awaiting signs of the long rains to supply their rainfall catchment system with a source of water that is more economical than hiring a tanker truck to deliver it. You, too, can keep track of St. Williams’ rainfall on the TAHMO data portal here – just plot precipitation and I hope you’ll see that the rains have finally begun!



Visiting the schools of western Kenya: Koyoo, Kachar, Homa Bay, and Kadie

20 Mar

I’m not exaggerating when I say it’s hot in Kisumu, Kenya. On March 10th, we saw its hottest day on record, 37o C. Kisumu, my home for the month, is located on the eastern shores of Lake Victoria. It lies in a woodland savannah ecoregion with two distinct rainy seasons – one in March and April and another in the fall. Outside the city, the third largest in Kenya, people fish or rely on subsistence farming in homesteads that sprinkle the landscape.

Just south of Kisumu, TAHMO began its School-2-School project in earnest last spring when Zach Dunn installed our first school weather station. TAHMO piloted the program at Koyoo Mixed Secondary School, near Rangwe, and partnered Koyoo with East Boise Jr. High in Idaho. This March, I’ve come to Kenya to visit Koyoo and several other schools as the program expands. The goal of TAHMO is to install low-cost, robust weather stations across sub-Saharan Africa in response to the critical need for weather data in a region where livelihoods are particularly vulnerable to climate change. While doing so, TAHMO is also committed to enhancing primary and secondary education by using schools to host our stations and creating science, technology, geography, and math related educational resources for teachers. Using TAHMO weather stations provides schools with hands-on material for lessons, and partnering with TAHMO ‘sister schools’ from the U.S.A. creates the excitement and motivation that accompanies cultural exchange.

TAHMO’s S2S program published its first set of teacher resources in January of 2015; these lesson plans were designed to help teachers in low-resource contexts use innovative ideas and go beyond theoretical learning, such as allowing students to download and analyze their local weather data. This past week I visited four schools throughout western Kenya, meeting teachers, assessing future school sites, and testing TAHMO’s hands-on lessons with students. During the way, I interviewed 10 teachers to better understand their perspectives, how they gather and incorporate new material into their lessons, and the obstacles they face to increasing the use of applied activities in the classroom. I also trained teachers from Koyoo and Homa Bay High on how to access data from their TAHMO weather station and use it to discuss the local environment with their students. Koyoo’s staff was eager to look up the data from their weather station online and compare notes with East Jr. High – and maybe put to rest the mysteries of life on a cold snowy winter day from their seats in a hot and dry classroom.

As TAHMO’s S2S program moves forward, we are working with teachers and encouraging them to share their most successful lesson plans on TAHMO’s resource portal. Many teachers I met wished they could use field trips, chemistry experiments, computer work, or school gardens to improve their students’ experiences. They wanted to ground topics in the real-world, but felt they could only use demonstrations methods due to their resource constraints. Despite these challenges, the same teachers had great ideas to share with one another for explaining concepts and engaging students with the limited materials available. Their passion was incredible. By tailoring our lesson plans to low-cost activities within the curriculum of Kenyan teachers, and spreading well-tested lessons contributed by fellow teachers, I think TAHMO could become a great educational tool for our partner schools!


A week of Early Warning Systems

Walking up the to UN building in Nairobi.

Walking up to the UN building in Nairobi.

Almost one year ago a severe mudslide devastated the community around Oso, in Washington State, making news headlines in my home region of the Pacific Northwest and across the country. In Uganda, deadly landslides happen every year as deforested mountainous regions experience heavy seasonal rainfall. These landslides leave hundreds dead and thousands homeless. Flooding, lightning strikes, landslides, severe droughts, and tsunamis are all examples of the power of nature, and a reminder of the importance of emergency preparedness and response.

When I headed back to graduate school 2 years ago and begin to work with TAHMO, the Trans African Hydro-Meteorological Observatory, I delved into the world of weather and climate. Weather information had never been on the forefront of my motivation to study Water Resource Engineering; its routine role in my daily check for a “rain pants addition” was taken for granted. As I learned about the dearth of weather data across sub-Saharan Africa, a region particularly vulnerable to climate change, I began to see the many uses these data play for weather nowcasting and forecasting, contributing both to useful information on ‘how to dress in the morning’ as well as critical knowledge of pending hydrological and meteorological hazards due to severe weather. Through the generosity of OSU’s Humanitarian Engineering program, I embarked on a trip to East Africa to gather first-hand experience with the climate issues faced and the need for weather data.

During my first weeks in Kenya, I was fortunate enough to attend two conferences focusing on weather and climate information, early warning systems, and climate adaptation. In early March, I joined as the UN’s CIRDA program convened representatives from 11 of the least developed countries in Africa in Kampala, Uganda. We discussed the role of partnerships between private companies, NGOs, and the academic sector in enabling better collection and application of climate data. TAHMO was presented as an opportunity for national meteorological agencies to collect low-cost automatic weather data while educating the next generation of meteorologists, hydrologists, and climate scientists. I learned about the challenges different countries face in implementing weather and climate related programs; from lack of infrastructure and sensor equipment to the inadequacy of political mandates which promote such work. Despite the challenges, each country had detailed plans to install weather stations, employ SMS and other communication alerting systems, and improve local capacity for weather data analysis through trainings and education.

As a contrast to CIRDA’s country-focused approach, I also attended a workshop in Nairobi hosted by the UN’s Clim-WARN project. This science based group shared tools and resources available to integrate into a multi-hazard global early warning system. Clim-WARN’s thorough assessment of both men and women in rural and urban settings of Ghana, Burkina Faso, and Kenya to better understand the best methods of communication and hazard-related vulnerabilities experienced by different target groups was a backdrop to the conversation on application of tools and resources. Finally, a key take-away reminded me of my King Elementary School days when we crouched in lines along the hallways during tornado or hurricane drills: educating stakeholders of actionable responses to early warning information is a key to ensuring the effectiveness of these systems.

Reflecting on the discussions had and information I learned about EWS and climate adaptation, I am more convinced than ever about the importance of weather data and it’s far reaching utility. I’m excited to work these ideas into my conversations with students and teachers when talking about “why should we install a weather station?”

I learned how to use a circular saw and perfected my sanding this past Saturday. I won’t post about HOW-TO build these, since the details are well outlined on this home depot post, but let’s just say it is definitely worth it!

DT worrying away...

Boston. Running. Not stopping.

7 May

Boston. Running. Not stopping.

Me, 3 weeks after the Boston Marathon. A personal best of 3:28:21, 6000 places ahead of where I was seeded. I thought I’d train like crazy (which I mostly did), PR (which I did), and quit running for a while. Yeah, right.

New challenge: How many of my family and friends can I get to qualify for Boston 2014? Did a local Burns Park 5k the other day to get me back in the spirit, a race my parents dragged my brother to in his middle school pre-running days… Nothing like seeing folks awake early on a Sunday to enjoy the neighborhood, the springtime, and running. I suppose I can’t stop running for a while.

dang it.

How toxic is your nail polish really?

I mean, I knew. But that just nicely reiterates why I need to stop with my not-so-secret relaxation method of painting my nails. (Maybe it’s the toxic fumes that are relaxing me so much?) Okay new Seche Vite polish from my cousin, you’re done! (Or should I at least wait I finish these last bottles before I quit? I hate to be wasteful…) 

crafts, march madness, and getting myself together.

25 Mar

This last week has been good.

1. I came to a new clarity with impulse driven second order differential equations while listening to “protest music” as my dad called it. (It was actually just the awesome song from Les Mis, ‘Can you hear the people sing?‘ that I had going on a very loud repeat…)

2. I ran 23 miles with the PR Fitness group and survived! Then I gorged on chocolate covered caramel corn and watched a GREAT film: The Central Park Five. I openly apologize to those of you next to me at the A2 Film Fest, I tried to keep my sobs to a faint hiccup but ’twas hard. I also developed an infatuation with Ken Burns and can’t stop talking about his “articulate, thoughtful and eloquent commentary”. 

3. STRONG KIDS is going Strong! Here we come final week, and I’m only $200 from my goal! It’s going to happen, I’m highly optimistic.

4. I love basketball, thus March rocks.

5.. I’ve been crafting up a storm. Photographic evidence:
