National Centers for Environmental Prediction (NCEP) and the European Center for Medium-Range Weather Forecasts (ECMWF). It is widely accepted that direct assimilation of radiance observations from microwave temperature sounding channels can significantly improve the accuracy of global and regional weather analysis and forecasts ( Andersson et al. 1994 ; Courtier et al. 1998 ; Derber and Wu 1998 ; McNally et al. 2000 ; Kozo et al. 2005 ). An initial evaluation of FY-3A MWTS against NOAA-18 AMSU

1. Introduction As one of major components in the water cycle and closely related to our daily life, precipitation has been a focus of study and observation since early human history. However, only in recent decades have rain observations become near-globally available thanks to the technologies of space-borne passive microwave radiometers and radar ( Wilheit 1986 ; Kummerow et al. 1998 ; Iguchi et al. 2000 ). The major advantage of space-borne radar and microwave radiometers is that they

thick clouds. Continuous ground-based radiometric profiler observations can be used to fill the temporal gaps between radiosonde soundings. Although ground-based infrared sounding systems show promise ( Feltz et al. 2003 ), microwave radiometers have a broader capability and can generally provide profiles during cloudy and light-precipitating conditions. This paper examines the measurement capabilities of a 12-channel microwave radiometer profiler (MWRP). A general description of ground

, the profiler seems well suited to reconstruct the melting layer structure upward from the completely melted stage. The drawbacks of this methodology are that the measured quantities are only indirectly related to the extinction profile and that the frequency of the profiler is significantly lower than those used by current microwave radiometers. Nevertheless, if the profiler observations can be correctly reproduced by a physical model, then we can have confidence that both the microphysical

1. Introduction Ground-based observations of the relatively weak microwave line of ozone at 11.072 454 5 GHz ( Pickett et al. 1998 ) in the upper mesosphere using low-cost satellite TV electronics have been made by the education project known as “The Mesospheric Ozone System for Atmospheric Investigations in the Classroom” (MOSAIC). Along with the primary goal of providing locally acquired data to aid in the teaching of data analysis methods and statistics to high school students, MOSAIC

this relationship, it turns out, is quite sensitive to storm system dynamics. The modern era of satellite observations emphasizes the importance of understanding this relationship even more thoroughly. The launch of the GPM ( Hou et al. 2014 ) core satellite, with a dual-frequency precipitation radar (DPR) and the most accurate microwave imager to date (GMI), affords the opportunity to intercalibrate a multitude of PMW radiometers to the same reference. Blended products of global rainfall

and climatological behavior. As an alternative, remote sensing from satellites is capable of global observation. Spaceborne observations such as passive microwave ( Cecil 2009 ; Cecil and Blankenship 2012 ; Ferraro et al. 2015 ) and visible and infrared measurements ( Bauer-Messmer and Waldvogel 1997 ; Ravinder et al. 2013 ; Merino et al. 2014 ) can be exploited to get a more comprehensive mapping of hail occurrence. In the current literature, passive channels are utilized in different

1. Introduction The Suomi National Polar-Orbiting Partnership ( SNPP ) satellite was successfully launched into a sun-synchronous polar orbit on 28 October 2011 with an equator crossing time of 1330 local time. The Advanced Technology Microwave Sounder (ATMS) onboard SNPP is a new cross-track and line-scanning microwave radiometer. The ATMS combines the functionalities of the previous Advanced Microwave Sounding Unit A (AMSU-A) and Microwave Humidity Sounder (MHS) into a single instrument

critical for hydrometeorological prediction, it is practically impossible to achieve useful monitoring or predictive skill if rainfall is not detected in the right catchment basin ( Kim and Barros 2001 ). This challenge is particularly acute in regions where the topography is complex and the representative ground-based rainfall observations are scarce. The precipitation radar (PR) and the Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) on board the TRMM satellite provide rainfall
