Besides brightness temperature and backscattering coefficient, microwave indices, defined as a combination of data collected at different frequencies and polarizations, revealed a good sensitivity to hydrological cycle parameters such as surface soil moisture, vegetation water content, and snow depth and its water equivalent. The differences between microwave backscattering and emission at more frequencies and polarizations have been well established in relation to these parameters, enabling operational retrieval algorithms based on microwave indices to be developed. This Special Issue aims at providing an overview of microwave signal capabilities in estimating the main land parameters of the hydrological cycle, e.g., soil moisture, vegetation water content, and snow water equivalent, on both local and global scales, with a particular focus on the applications of microwave indices. 606 $aGeography$2bicssc 610 $atime series analysis 610 $apassive microwave soil moisture 610 $aSentinel-1 and Sentinel-2 610 $aSnow Depth and Snow Water Equivalent 610 $asnow cover characteristics 610 $avegetation biomass 610 $aroughness 610 $asea ice 610 $aSMOS 610 $amicrowave radiometry 610 $asoil moisture downscaling 610 $aVegetation Biomass 610 $avegetation index 610 $aTerra MODIS 610 $aSentinel-1 610 $aMicrowave Indices 610 $asoil moisture content 610 $adual-frequency ratios 610 $aSMAP 610 $apassive microwave 610 $awater-cloud model 610 $asnow 610 $aSentinel-1 backscatter 610 $aAMSR2 610 $adata fusion 610 $amicrowaves 610 $amountain region 610 $aSAR 610 $astart of season 610 $acrops 610 $aNDVI 610 $ascatterometer 610 $aRadarsat-2 610 $apolarization 610 $avegetation water content 610 $aco-pol ratio 610 $aactive microwaves 610 $amicrowave indices 610 $aharvest 610 $aMicrowave Radiometry 610 $asoil moisture 610 $aSoil Moisture Content 610 $asnow correlation length 610 $aradiometer 610 $aradar 610 $asoil scattering 610 $avegetation descriptor 610 $ascale gap 610 $asnow water equivalent 615 7$aGeography 700 $aPaloscia$b Simonetta$01787925 702 $aSanti$b Emanuele 801 0$bScCtBLL 801 1$bScCtBLL 906 $aBOOK 912 $a9910367751603321 996 $aMicrowave Indices from Active and Passive Sensors for Remote Sensing Applications$94322004 997 $aUNINA
