Investigation of the adiabatic assumption for estimating cloud micro- and macrophysical properties from satellite and ground observations [PDF]

Atmospheric Chemistry and Physics, 2016
Cloud properties from both ground-based as well as from geostationary passive satellite observations have been used previously for diagnosing aerosol–cloud interactions. In this investigation, a 2-year data set together with four selected case studies

Improving the altimetric rain record from Jason-1 & Jason-2 [PDF]

, 2010
Dual-frequency rain-flagging has long been a standard part of altimetric data analysis, both for quality control of the data and for the study of rain itself, because altimeters can provide a finer spatial sampling of rain than can passive microwave ...

An integrated approach toward the incorporation of clouds in the temperature retrievals from microwave measurements [PDF]

Atmospheric Measurement Techniques, 2014
In this paper, we address the characterization of clouds and its inclusion in microwave retrievals in order to study its effect on tropospheric temperature profiles measured by TEMPERA radiometer.

Measurement of Solar Absolute Brightness Temperature Using a Ground-Based Multichannel Microwave Radiometer

Remote Sensing, 2021
Ground-based multichannel microwave radiometers (GMRs) can observe the atmospheric microwave radiation brightness temperature at K-bands and V-bands and provide atmospheric temperature and humidity profiles with a relatively high temporal resolution ...

Retrieval of tropospheric water vapour by using spectra of a 22 GHz radiometer [PDF]

Atmospheric Measurement Techniques, 2011
In this paper, we present an approach to retrieve tropospheric water vapour profiles from pressure broadened emission spectra at 22 GHz, measured by a ground based microwave radiometer installed in the south of Bern at 905 m.

Cloud optical depth retrievals from the Aerosol Robotic Network (AERONET) cloud mode observations [PDF]

, 2010
Cloud optical depth is one of the most poorly observed climate variables. The new “cloud mode” capability in the Aerosol Robotic Network (AERONET) will inexpensively yet dramatically increase cloud optical depth observations in both number and accuracy ...
