First Contact (for the Parsivel and MRR) Five members of SPADE worked tirelessly throughout the day to connect a Parsivel and a MRR to the existing Nipika weather station. After a beautiful data download from the weather station, we subsequently struggled to incorporate two fancy new additions to the existing entourage of instruments. With no power source outside of the weather station solar panels, we were forced to delve into inventive new wiring schematics to increase the power supply for our two new friends with a brand new solar panel. Success came late in the day, and proper testing remains, but it looks like we will be able to successfully grow our family of weather instruments at this location. Other highlights of the day included a warm welcome by Lyle Wilson, the owner of Nipika Resorts, some brief flurries of graupel, and several visits from a brave little bird that tried to make a home out of our truck. Today, Nipika greeted us with a whole host of weather features. Sometimes we found ourselves bathing in gentle sunshine, with blue skies overhead and little wind. At other points we were rushing to protect our more sensitive electronics from sudden bursts of wind and precipitation. Overall, we had a fruitful day of learning in a spectacular outdoor laboratory

Another Snowy Day
We arrived on site at Fortress around 1630 UTC. It was a couple hours before the precipitation started but it gave us some time to double check the equipment and complete some tasks that we were putting off. Precipitation was on and off throughout the day. Sometimes it was too light to take macrophotography pictures and other time it was heavy with large aggregates! It made for a more interesting day than the day before! Temperatures were fairly cool at the top and we saw rimed snow and graupel. Winds were fairly light the entire day. Around 2130 UTC we got a report that it was raining in Canmore (thanks Julie!), so we decided to do a carsonde so that we could capture a transition region down the mountain in case it was raining at the bottom. Unfortunately, that was not the case and it snowed the whole way. Oh well. But it was good practice for Charlie and Cécile – they are prepared for the next opportunity! Meanwhile, precipitation was very heavy at the top with large aggregates. We continued taking measurements for the next few hours. After checking the models and radar, we determined that precipitation was ending or would be very light around 0100 UTC on May 1, and so we left Fortress shortly after that. Precipitation actually ended around 0230 UTC. Snow depth measurements indicate that we got around 5 cm – 7 cm over the course of the day.
Special thanks to Mel for sharing his birthday cake with us!!!
