Multiyear variability of ice concentration in the White Sea according to satellite data

Лëд и снег, 2023
The objectives of this study were to analyze satellite data on the ice conditions in the White Sea available for the period 1979-2021 so that to identify statistically significant trends in closeness of ice during that period, and to establish spatial ...

Assessment of the NASA AMSR-E SWE Product

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2010
Since the launch of the Scanning Multichannel Microwave Radiometer (SMMR) in 1978, several studies have demonstrated the capability of spaceborne passive microwave sensors for mapping global snow water equivalent (SWE). Currently, SWE values are estimated operationally from microwave brightness temperatures measured by the Advanced Microwave Scanning ...

Influence of cracking clays on satellite estimated and model simulated soil moisture [PDF]

Hydrology and Earth System Sciences, 2010
Vertisols are clay soils that are common in the monsoonal and dry warm regions of the world. One of the characteristics of these soil types is to form deep cracks during periods of extended dry, resulting in significant variation of the soil and ...

An Analysis of Arctic Sea Ice Leads Retrieved from AMSR-E/AMSR2

Remote Sensing, 2022
In this study, we retrieve an Arctic sea ice lead fraction from AMSR2 passive microwave data in winter from 2012 to 2020 based on an algorithm developed for AMSR-E data. The derived AMSR2 sea ice lead fraction is validated against MODIS images.
