Diurnal Variation of Liquid Water Path Derived From Two Polar‐Orbiting FengYun‐3 MicroWave Radiation Imagers

open access: yesGeophysical Research Letters, Volume 45, Issue 12, Page 6281-6288, 28 June 2018., 2018
Abstract MicroWave Radiation Imagers (MWRIs) onboard the afternoon FengYun‐3B (FY‐3B) and midmorning FengYun‐3C (FY‐3C) satellites provide global observations almost 4 times a day at any location. This study examines the diurnal cycle of the liquid water path (LWP) over the southeast Pacific Ocean using MWRI data. A double‐difference calibration method

Microwave Radiation

open access: yes, 2015
Microwave radiation is a form of electromagnetic radiation. It covers, broadly speaking, frequencies between 300 MHz and 300 GHz. For example a microwave oven operates at a frequency of 2.45 GHz and many mobile network providers use frequencies between ...

An Algorithm for Retrieving Precipitable Water Vapor over Land Based on Passive Microwave Satellite Data

open access: yesAdvances in Meteorology, Volume 2016, Issue 1, 2016., 2016
Precipitable water vapor (PWV) is one of the most variable components of the atmosphere in both space and time. In this study, a passive microwave‐based retrieval algorithm for PWV over land without land surface temperature (LST) data was developed.

Sea ice concentration derived from temperature brightness data of the Microwave Radiation Imager sensors onboard the Chinese FengYun-3 satellites in the polar regions from 2010 to 2019

open access: yes, 2022
This sea ice concentration dataset (SIC) was derived from the re-calibrated brightness temperature of the Microwave Radiation Imager (MWRI) sensors. The MWRI sensors are onboard the Chinese second generation of sun-synchronous meteorological satellites ...

Enhanced Retrieval of Spring Snow Depth Over Pan‐Arctic Sea Ice From AMSR2 Observations for 2013–2023 Using Multi‐Model Machine Learning

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Snow on sea ice modulates the Earth's radiation budget and sea ice mass balance, yet satellite retrievals of Arctic snow depth remain subject to substantial algorithmic uncertainty. We develop a multi‐model machine learning (ML) framework for retrieving spring snow depth over Arctic sea ice from Advanced Microwave Scanning Radiometer 2 (AMSR2).

Time Series Consistency of Passive Microwave Sensors (1978–2023) Brightness Temperature Data for Snow Depth Estimation

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Passive microwave remote sensing offers all-weather, all-day observations, but sensor inconsistencies hinder long-term continuity and multisensor integration for surface parameters estimation. This study proposed methods to improve brightness temperature

How Can FengYun—3G Satellite Precipitation Radar and Microwave Imager Unveil Multi—Phase Hydrometeors?

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The observations from Precipitation Measurement Radar (PMR) and Microwave Radiation Imager (MWRI‐RM) onboard FengYun‐3G satellite are first time utilized to derive multi‐phase hydrometeors in clouds. The FY‐3G hydrometeor retrieval algorithm utilizes the Advanced Radiative Transfer Modeling System (ARMS) as its core module. It incorporates PMR‐
