Ice-phase Precipitation Retrievals over Land Using Combined Radar / Radiometer Satellite Observations
Passive microwave (PMW) measurements of ice-phase precipitation, such as snowfall and graupel, provide a physically direct basis for inferring the integrated amount of precipitation within a given field-of-view (FOV), assuming that other sources of noise can be adequately accounted for. However, the vertical distribution of precipitation within the FOV is generally unknown. By combining passive...
متن کاملIce Cloud Retrievals and Analysis with the Compact Scanning Submillimeter Imaging Radiometer and the Cloud Radar System during CRYSTAL FACE
Submillimeter-wave radiometry is a new technique for determining ice water path (IWP) and particle size in upper-tropospheric ice clouds. The first brightness temperatures images of ice clouds above 340 GHz were measured by the Compact Scanning Submillimeter Imaging Radiometer (CoSSIR) during the Cirrus Regional Study of Tropical Anvils and Cirrus Layers (CRYSTAL) Florida Area Cirrus Experiment...
متن کاملIdentification of hydrometeors and other targets by dualpolarization radar
Whereas different hydrometeor types cannot be readily distinguished using radar reflectivity alone, this paper shows how the differential reflectivity available from dual-polarization radars can be used as an indicator of hydrometeor type (when supported by reflectivity factor also), and that the spatial variability of differential reflectivity is a useful addition. Various hydrometeor types, g...
متن کاملValidation of AMSR Snow Depth on Sea Ice Retrievals Using an Airborne Pulse Radar: Final Report
This is the final report on the project entitled “Validation of AMSR snow depth on sea ice retrievals using an airborne pulse radar.” This is a collaborative project between the Center for Remote Sensing of Ice sheets (CReSIS) at the University of Kansas and NASA Goddard Space Flight Center (GSFC). We designed and developed ultrawideband radars for measuring thickness of snow over sea ice from ...
متن کاملDual-frequency radar ratio of nonspherical atmospheric hydrometeors
[1] Dual-frequency cloud and precipitation radar systems are being actively developed and installed on different platforms. The use of two radar frequencies (with at least one frequency outside the Rayleigh type of scattering for hydrometeors of interest) allows independent estimates of hydrometeor effective size. With these estimates, radarbased retrievals of such important parameters as cloud...
