Remote Sensing, Model-Derived and Ground Measurements of Snow Water Equivalent and Snow Density in Alaska
Snow water equivalent (SWE) is important for investigations of annual to decadal-scale changes in A and energy-water cycles. Passive microwave satellite-based retrieval algorithm estimates of SWE now sp three decades. SWE retrievals by the Advanced Microwave Scanning Radiometer for the Earth Ob (AMSR-E) onboard the NASA-Aqua satellite ended at October 2011. A critical parameter in the AM gorith...
متن کاملCorrelation and Prediction of Snow Water Equivalent from Snow Sensors
Since 1982, under an agreement between the California Department of Water Resources and the USDA Forest Service, snow sensors have been installed and operated in Forest Service-administered wilderness areas in the Sierra Nevada of California. The sensors are to be removed by 2005 because of the premise that sufficient data will have been collected to allow "correlation" and, by implication, pre...
متن کاملModeling bulk density and snow water equivalent using daily snow depth observations
Bulk density is a fundamental property of snow relating its depth and mass. Previously, two simple models of bulk density (depending on snow depth, date, and location) have been developed to convert snow depth observations to snow water equivalent (SWE) estimates. However, these models were not intended for application at the daily time step. We develop a new model of bulk density for the daily...
متن کاملChanges in seasonal snow water equivalent distribution in High Mountain Asia (1987 to 2009)
Snow meltwaters account for most of the yearly water budgets of many catchments in High Mountain Asia (HMA). We examine trends in snow water equivalent (SWE) using passive microwave data (1987 to 2009). We find an overall decrease in SWE in HMA, despite regions of increased SWE in the Pamir, Kunlun Shan, Eastern Himalaya, and Eastern Tien Shan. Although the average decline in annual SWE across ...
