Comparison Among the Atmospheric Boundary Layer Height Estimated From Three Different Tracers [PDF]

open access: yesEPJ Web of Conferences, 2020
The Atmospheric Boundary Layer (ABL) is the lowermost part of the troposphere. In this work, we analysed the combination of ABL height estimated continuously by three different remote sensing systems: a ceilometer, a Doppler lidar and a passive Microwave

Microwave radiometry in monitoring and emergency mapping of water seepage and dangerously high groundwaters

open access: yesJournal of Telecommunications and Information Technology, 2023
Detailed and geo-referenced maps identifying the locations of saturated and dry levees can be produced using microwave radiometric measurements from a light aircraft or helicopter, and integrated with GPS for positioning and orientation. The development

Passive Microwave Remote Sensing of Snowpacks

open access: yesPROCEEDINGS OF HYDRAULIC ENGINEERING, 1991
Both theory and experiment in passive microwave remote sensing of snow have been studied. Synchronizing the airborne experiments using Microwave Scanning Radiometer (MSR) with the passing days of Marine Observation Satellite 1 (MOS-1), ground truth data were obtained around Asahikawa of Hokkaido during February 1988.

Retrieving Precipitable Water Vapor Over Land From Satellite Passive Microwave Radiometer Measurements Using Automated Machine Learning

open access: yesGeophysical Research Letters, 2023
Accurately retrieving precipitable water vapor (PWV) over wide‐area land surface remains challenging. Unlike passive infrared remote sensing, passive microwave (PMW) remote sensing provides almost all‐weather PWV retrievals.

Estimating annual water storage variations in medium-scale (2000–10 000 km2) basins using microwave-based soil moisture retrievals [PDF]

open access: yesHydrology and Earth System Sciences, 2017
Due to their shallow vertical support, remotely sensed surface soil moisture retrievals are commonly regarded as being of limited value for water budget applications requiring the characterization of temporal variations in total terrestrial water storage
