Global precipitation measurement (GPM) progress

SPIE Proceedings, 2005
Global Precipitation Measurement (GPM) is an international Earth observing "System of Systems" that will initiate the measurement of precipitation, a key climate factor, globally. GPM is a joint initiative with the Japan Aerospace Exploration Agency (JAXA) and other international partners.

Global precipitation measurement (GPM) status

SPIE Proceedings, 2004
Global Precipitation Measurement (GPM) is a global space endeavor conceived by the US and Japan that has sparked global interest. Building upon the success of the Tropical Rainfall Measuring Mission (TRMM), it will initiate the measurement of global precipitation, a key climate factor.

Global Precipitation Measurement (GPM) development

SPIE Proceedings, 2006
Understanding the Earth's climate and how it responds to climate perturbations relies on knowledge of how atmospheric moisture, clouds, latent heating, and the large-scale circulation vary with changing climate conditions. The physical process that links these key climate elements is precipitation.

Potential of the Global Precipitation Measurement Constellation for Characterizing the Polar Firn

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
This paper discusses the utilization of the Global Precipitation Measurement (GPM) constellation as a single multi-frequency radiometer to profile subsurface properties of the polar firn. Initial analyses focusing on the Concordia station in Antarctica have demonstrated that GPM brightness temperature measurements can be successfully simulated across a

Global Precipitation Measurement (GPM) L-6

SPIE Proceedings, 2013
The Global Precipitation Measurement (GPM) mission will advance the measurement of global precipitation, making possible high spatial resolution precipitation measurements. GPM will provide the first opportunity to calibrate measurements of global precipitation across tropical, mid-latitude, and polar regions.

Vicarious Calibration of Global Precipitation Measurement Microwave Radiometers

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
The vicarious cold calibration method of Ruf has been used to assess the calibration of the TMI, WindSat, SSM/I F13 and SSM/I F14 microwave radiometers using data from the GPM Inter-Calibration Working Group. Significant scan position dependent biases are seen for TMI (as large as 1 K) and for WindSat (as large as 5 K)-scan position dependent biases in
