CloudSat's return to the A-Train

International Journal of Space Science and Engineering, 2013
This paper discusses CloudSat rejoining the A-Train after multiple faults from a severe battery anomaly on April 17th 2011 left the vehicle in a power-positive, but passive state. After diagnosing the anomaly, the CloudSat team developed and tested a new method of operations which limited active operations to the sunlit portion of the orbit.

Status of the CloudSat Mission

2020
This chapter provides an overview of the CloudSat mission as it relates to precipitation remote sensing. We describe how the Cloud Profiling Radar (CPR) contributes to the global observing system through precise precipitation detection, quantification of snowfall rate, quantification of light rain fall, and stratiform/convective delineation. We provide

CloudSat Precipitation Profiling Algorithm—Model Description

Journal of Applied Meteorology and Climatology, 2010
AbstractIdentifying and quantifying the intensity of light precipitation at global scales is still a difficult problem for most of the remote sensing algorithms in use today. The variety of techniques and algorithms employed for such a task yields a rather wide spectrum of possible values for a given precipitation event, further hampering the ...

CloudSat: The Cloud Profiling Radar Mission

2006 CIE International Conference on Radar, 2006
The Cloud Profiling Radar (CPR), the primary science instrument of the CloudSat Mission, is a 94-GHz nadir-looking radar that measures the power backscattered by clouds as a function of distance from the radar. This instrument will acquire a global time series of vertical cloud structure at 500-m vertical resolution and 1.4-km horizontal resolution ...

Correcting Biased Evaporation in CloudSat Warm Rain

IEEE Transactions on Geoscience and Remote Sensing, 2017
The CloudSat mission’s Cloud Profiling Radar has provided the first global-scale estimates of light rainfall from warm marine clouds. Because surface radar reflection prevents hydrometeor detection below ~720 m, the CloudSat 2C-RAIN-PROFILE retrieval uses an evaporation–sedimentation model to extend its profile estimates to the surface. We use in situ

THE CLOUDSAT MISSION AND THE A-TRAIN

Bulletin of the American Meteorological Society, 2002
CloudSat is a satellite experiment designed to measure the vertical structure of clouds from space. The expected launch of CloudSat is planned for 2004, and once launched, CloudSat will orbit in formation as part of a constellation of satellites (the A-Train) that includes NASA's Aqua and Aura satellites, a NASA–CNES lidar satellite (CALIPSO), and a ...

A comparison between CloudSat and aircraft data for a multilayer, mixed phase cloud system during the Canadian CloudSat‐CALIPSO Validation Project

Journal of Geophysical Research, 2008
Reflectivities recorded by the W‐band Cloud Profiling Radar (CPR) aboard NASA's CloudSat satellite and some of CloudSat's retrieval products are compared to Ka‐band radar reflectivities and in situ cloud properties gathered by instrumentation on the NRC's Convair‐580 aircraft.

A climatology of tropical congestus using CloudSat

Journal of Geophysical Research: Atmospheres, 2013
AbstractCumulus congestus clouds have long been identified as an important part of the spectrum of convective clouds in the tropics. These clouds—which range in size from growing cumulus to slightly smaller than a cumulonimbus—make important contributions to precipitation and latent heat fluxes in the tropics.

CloudSat and the EOS constellation

IGARSS 2001. Scanning the Present and Resolving the Future. Proceedings. IEEE 2001 International Geoscience and Remote Sensing Symposium (Cat. No.01CH37217), 2002
CloudSat is a multi-satellite satellite experiment designed to utilize the opportunity provided by the EOS constellation to deliver, as-directly as possible, information relevant for assessing the way cloud processes are parameterized in global weather prediction and climate models. In this way, CloudSat will provide a means for the critical evaluation

Near-Real-Time Applications of CloudSat Data

Journal of Applied Meteorology and Climatology, 2008
Abstract Within 2 months of its launch in April 2006 as part of the Earth Observing System A-Train satellite constellation, the National Aeronautics and Space Administration Earth System Science Pathfinder (ESSP) CloudSat mission began making significant contributions toward broadening the understanding of detailed cloud vertical ...
