Microwave radiometer linearity measured by simple means [PDF]

IEEE International Geoscience and Remote Sensing Symposium, 2003
Modern spaceborne radiometer systems feature an almost perfect on-board calibration, hence the primary calibration task to be carried out before launch is a check of radiometer linearity. This paper describes two ways of measuring linearity of microwave radiometers only requiring relatively simple equipment.

Impact of Moist Thermodynamic Formulations on Climatological Temperature Fields in a Global Cloud‐Resolving Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract This study investigates how climatological temperature fields in simulations are influenced by the choice of moist thermodynamic formulations. Two formulations were compared: one developed to ensure internal thermodynamic consistency, and a simpler approximation similar to those commonly used in meteorological and climate models.

Effects of Assimilating Ground-Based Microwave Radiometer and FY-3D MWTS-2/MWHS-2 Data in Precipitation Forecasting

Remote Sensing
This study investigates the impacts of the joint assimilation of ground-based microwave radiometer (MWR) and FY-3D microwave sounder (MWTS-2/MWHS-2) observations on the analyses and forecasts for precipitation forecast.

Development of an IEEE Standard for Calibration of Microwave Radiometers

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
In January 2019 a Project Authorization Request was submitted to the IEEE standards association with the title "Standard for Calibration of Microwave Radiometers in the 300 MHz to 1 THz Frequency Range for Geoscience Applications". An open committee is being assembled to draft this standard with the purpose of unifying and documenting calibration ...

Improving Inter‐Satellite Tropical Cyclone Precipitation Consistency by Deep Learning

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Global Precipitation Measurement mission satellite constellation comprises multiple satellites that produce widely used global tropical cyclone precipitation estimates. The quality of precipitation estimates among these satellites varies significantly due to differences in mission purpose, channel availability, and spatial resolution ...

Determination of low-level temperature profiles from microwave radiometer observations during rain [PDF]

Atmospheric Measurement Techniques
Usually, microwave radiometer observations have to be discarded during rain. The radomes of the receiver antenna get wet, which hampers accurate measurements since the retrieval algorithms to derive atmospheric quantities are not trained for rain events.

Snow Depth on Arctic Sea Ice Retrieval Using a Synergy of Sentinel‐3's Active and Passive Microwave Instruments

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Snow depth remains one of the largest sources of uncertainty in satellite‐derived sea ice thickness (SIT). Here, we introduce the novel Nadir Radiometer and Radar Synergy (NaRRS) method that combines data from Sentinel‐3's Microwave Radiometer (MWR) and Synthetic Aperture Radar Altimeter (SRAL) to retrieve Arctic snow depth on sea ice.

Machine Learning Reveals Hidden Bias in ERA5 Cloud Heights Over Earth's Third Pole

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Accurate cloud base height (CBH) over the Tibetan Plateau—Earth's Third Pole—is essential for monsoon dynamics, glacial melt, and water security, yet ERA5 systematically underestimates it. Here, we present a two‐step machine learning framework to mitigate this hidden bias.
