The Smoke-Screen: An Open-Source Visualizer of CALIPSO Data

Atmospheric scientists analyze satellite data as part of their assessments of atmospheric health. One such satellite, the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO), outputs images of longitudinal cross-sections of the Earth’s atmosphere. Depending on the wavelength of light used in the observation, it is possible to detect the presence of various aerosols. Some are natural sources, like dust storms, and sulfur dioxide from volcanos.

Hot Potato: Preserving Traditional Farming in the Peruvian Andes

Agricultural systems in tropical montane regions are particularly vulnerable in the face of global climate change. Anecdotal evidence from Parque de la Papa, located in the Peruvian Andes, indicates that farmers following traditional practices have moved potato crops to higher elevations seeking suitable growing conditions for the potato varieties they have cultivated for centuries.

Rain or Snow: Precipitation Estimation in the Mountainous West

Shifting hydrologic processes have become a significant problem in California, Oregon, and Washington. In recent years, average winter temperatures have risen, spring snowmelt has occurred earlier, and a greater portion of precipitation has fallen as rain rather than snow in the Sierra Nevada and Cascade mountain ranges.
