Cloud‐Rain Vertical Inconsistency Increases IMERG Precipitation Uncertainty

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract IMERG accuracy is limited by the vertical inconsistency between satellite‐observed cloud‐top information and the true vertical structure of precipitation. Using FY‐3G Precipitation Measurement Radar (PMR) observations as reference and FY‐4B cloud‐top parameters, we investigate the vertical‐structure sources of IMERG retrieval errors during the

Pseudo‐Radar Reflectivity by Applying U‐Net Models to Global Passive Microwave Brightness Temperatures

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Spaceborne radar systems such as the Global Precipitation Measurement Mission (GPM)'s core satellite Dual‐frequency Precipitation Radar (DPR) provide global insight into precipitation structure, storm morphology, and hydrological cycles. However, their limited spatial and temporal sampling and high cost constrain their ability to continuously ...

Organic matter respiration stoichiometry in the Arctic Ocean is linked to shifts in plankton community composition

open access: yesLimnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract The global rate of ocean deoxygenation may be influenced by the molar ratio of dissolved oxygen to organic carbon consumed during microbial respiration. However, respiration stoichiometry and its environmental controls are not fully understood due to sparse direct measurements and limited global coverage.

Microwave Radiometer (MWR) Handbook [PDF]

open access: yes, 2006
The Microwave Radiometer (MWR) provides time-series measurements of column-integrated amounts of water vapor and liquid water. The instrument itself is essentially a sensitive microwave receiver. That is, it is tuned to measure the microwave emissions of the vapor and liquid water molecules in the atmosphere at specific frequencies.
