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

Interannual Variations of Vegetation Optical Depth are Due to Both Water Stress and Biomass Changes

Geophysical Research Letters, 2021
Microwave radiometry can be used to measure vegetation water content through vegetation optical depth (VOD). VOD can vary due to changes in water stress alone, but also scales with aboveground biomass.

Assimilation of vegetation optical depth retrievals from passive microwave radiometry [PDF]

Hydrology and Earth System Sciences, 2020
Vegetation optical depth (VOD) retrievals from passive microwave sensors provide analog estimates of above-ground canopy biomass. This study presents the development and analysis of assimilating VOD retrievals from X-, C-, and L-band passive microwave ...

Monitoring post-fire recovery of various vegetation biomes using multi-wavelength satellite remote sensing [PDF]

Biogeosciences, 2022
Anthropogenic climate change is now considered to be one of the main factors causing an increase in both the frequency and severity of wildfires. These fires are prone to release substantial quantities of CO2 into the atmosphere and to endanger natural ...

Low, fixed dose defibrotide in management of hepatic veno-occlusive disease post stem cell transplantation

Hematology/Oncology and Stem Cell Therapy, 2018
Objective/background: Hepatic veno-occlusive disease (VOD) is well recognized potentially serious regimen-related toxicity seen after stem cell transplantation. Severe VOD is associated with poor long-term outcomes with very high mortality.
