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 ...

Development of Continuous AMSR-E/2 Soil Moisture Time Series by Hybrid Deep Learning Model (ConvLSTM2D and Conv2D) and Transfer Learning for Reanalyses

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Surface soil moisture (SSM) is a crucial climate variable of the Earth system that regulates water and energy exchanges between the land and atmosphere, directly influencing hydrological, biogeochemical, and energy cycles. However, satellite-derived SSM,

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 ...

Effect of Structural Uncertainty in Passive Microwave Soil Moisture Retrieval Algorithm

Sensors, 2020
Passive microwave sensors use a radiative transfer model (RTM) to retrieve soil moisture (SM) using brightness temperatures (TB) at low microwave frequencies. Vegetation optical depth (VOD) is a key input to the RTM. Retrieval algorithms can analytically

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.
