NSIDC recovers rescued data and reveals sea ice secrets (video)

Garrett Campel

50 years ago, NASA launched Nimbus to study Earth from space. Now, experts at the National Snow and Ice Data Center (part of CIRES), are recovering valuable data and images from old, long-lost film, and expanding their understanding of sea ice in the Arctic and Antarctic. When NASA launched Nimbus-1 50 years ago, the agency’s key goals were to test instruments that could capture images of clouds and other meteorological features. The Nimbus satellites made such excellent observations, NASA eventually handed over key technologies to the National Oceanic and Atmospheric Administration … [Read more...]

CU-Boulder teams up with Mesa County to make snow-depth data free to water managers, farmers, public

Mesa County GPS Network

New from Colorado.edu: A University of Colorado Boulder professor who developed a clever method to measure snow depth using GPS signals is collaborating with Western Slope officials to make the data freely available to a variety of users on a daily basis. CU-Boulder aerospace engineering sciences Professor Kristine Larson and her colleagues discovered in 2009 that GPS signals that bounce off Earth’s surface before hitting the receivers, once considered bothersome “noise,” could be used to measure snow depth, soil moisture and even vegetation moisture. Larson also is a pioneer in the … [Read more...]

Keeping up with CU-Boulder Researchers in Antarctica

CU-Boulder researchers in Antarctica

The University of Colorado Boulder has multiple research projects going on in Antarctica every year. Here's a look at what teams from the Cooperative Institute for Environmental Sciences and the Institute of Arctic and Alpine Research are up to this season. The McMurdo Dry Valleys--the largest relatively ice-free zone on the Antarctic continent--has been studied as part of the National Science Foundation's Long-Term Ecological Research Network since 1993. The principal investigator on the project is Outreach Award recipient Diane McKnight, a fellow at CU-Boulder's Institute of Arctic and … [Read more...]
