To investigate the microwave radiation characteristics of different vegetation types, “pure pixels” 12 typical vegetated land types were selected and corresponding emissivity was retrieved under clear sky based on L1C AMSR2 observed brightness temperatures (TBs). According to values for spectral features in summer from 10.65 89 GHz analyzed first. Then, temporal variations at 10.65, 18.7, 36.5 ...

The surface effective emissivities of Arctic sea ice are calculated using Advanced Microwave Scanning Radiometer 2 (AMSR2) measurements. These analyzed for stable winter conditions during the months January–May and November December 2020 several main types defined with maps Antarctic Research Institute (AARI). derived from AMSR2 data radiation transfer model a non-scattering atmosphere ERA5 rea...

Detailed snow cover maps are essential for estimating the earth’s energy balance and hydrological cycle. Mapping across spatially extensive topographically complex areas with less or no cloud obscuration is challenging, but SNPP-VIIRS Day/Night Band (DNB) nighttime light data offers a potential solution. This paper aims to map distribution at 750 m resolution diverse 1,664,900 km2 of Xinjiang, ...

The Integrated Multisatellite Retrievals for GPM (IMERG) is designed to derive precipitation by merging data from all the passive microwave (PMW) and infrared (IR) sensors. While input source errors originating PMW IR sensors are important, their structure, characteristics, algorithm improvement remain unclear. Our study utilized a four-component error decomposition (4CED) method systematic ran...

Abstract The Joint Typhoon Warning Center (JTWC) utilized new space-based environmental monitoring (SBEM) data alongside traditional to adjust JTWC tropical cyclone (TC) intensity and structure estimates during production of the official 2019 Best Track dataset. Intensity from multiple platforms such as Advanced Microwave Scanning Radiometer-2 (AMSR2), Soil Moisture Active Passive (SMAP) Ocean ...
