Passive millimeter-wave retrieval of global precipitation utilizing satellites and a numerical weather prediction model
… (F([lambda])), to be used as a global precipitation ground-truth for evaluating alternative millimeter-wave satellite designs and for developing methods for millimeter-wave precipitation retrieval and assimilation. The model's predicted millimeter-wave atmospheric radiances were found …

Characterization of uncertainty in remotely-sensed precipitation estimates
Satellite-derived retrievals of precipitation have increased in availability and improved in quality over the last decade. There are now several satellites in orbit with instruments capable of precipitation retrieval with various degrees of accuracy, spatial resolution and temporal sampling. These …

Storm-wide precipitation retrievals
The monitoring of precipitation is important for scientific purposes, such as the study of world weather patterns, the development of global precipitation maps, and the tracking of seasonal and diurnal variations in precipitation rates. Over time many observation methods have been used to estimate …

A new snowfall detection algorithm for high latitude regions based on a combination of active and passive sensors
Precipitation retrieval over high latitudes, particularly snowfall retrieval over ice and snow, using satellite-based passive microwave spectrometers, is currently an unsolved problem. The challenge results from the large variability of microwave emissivity spectra for snow and ice surfaces, which …

Evaluations of microphysical parameterizations in retrieval algorithms for snowfall particle size distributions from dual frequency radar measurements
… Ku and Ka radar measurements from the Global Precipitation Measurement (GPM) satellite have the potential for novel retrievals of snowfall precipitation from space. These retrievals are dependent on assumptions that relate the maximum measured dimension of a snowflake to its mass and radar …
