Our project goal: to deploy an environmental sensor system (Snowcloud) to study effects of climate change in a high desert environment (Eastern Sierra). The Snowcloud system is low cost, low impact technology developed at UVM.
Several institutions were involved in this deployment. Here we are receiving delivery of the sensor station stands from VT Technical College. Barry Woodworth (far right) managed the fabrication there.
Stand materials were shipped prior to travel.
Sam, Sarah, and Jeff on the UVM deployment team, starting our journey west at Burlington airport.
While in CA, we stayed at SNARL, close to the deployment site.
A beautiful setting for field work.
Pleasant accommodations in the shadow of Mt. Morrison.

On day 2, Catherine Wade and Michael Loik (left) from UC Santa Cruz met us for physical deployment. UCSC is leading the environmental science component of the project.
On-site deployment involved hard work and cooperation over 4 days. Preparation took well over a year.

Sarah working on software issues in the CRT-friendly shade of "command central".
A completed sensor stand: solar recharged battery power, wireless mesh communication, multiple sensor modalities.
Snowcloud sensor stand features: an elevated sensor/control box for measuring snow depth, air temperature, light intensity, and battery voltage.
Snowcloud sensor stand features: a ground level sensor/control box with "under shrub" light intensity, and soil moisture at multiple levels.
Jeff turning on station 3. All sensor stations will collect and report data automatically through the Spring, unattended by humans.
All sensor stations communicate wirelessly to this "gateway" station, which reports data to the Internet. Sarah managed development of its control hardware and software, in black box. Note height of box, to allow access during Winter (lots of snow!)
Gateway innards: LAN connection board, cellmodem for reporting to Internet, and control board with SD card for local backup datalogging.
Last day, putting final touches on the completed, successful deployment.
