Sentences with phrase «microwave radiometer data»

This hindcast uses two time - varying inputs: 10 - meter wind vectors from the atmospheric model NAVGEM (Navy Global Environmental Model, Hogan et al. 2014) run at the Fleet Numerical Meteorology and Oceanography Center (FNMOC), and analyses of ice concentrations (also produced at FNMOC) from passive microwave radiometer data (SSM / I).

The satellite data come from the European Remote Sensing satellite scatterometers (ERS - 1 and ERS - 2), NASA scatterometers (NSCAT and Seawinds onboard ADEOS - 1 and QuikScat respectively), and several defense Meteorological Satellite Program (DMSP) radiometers (Special Sensor Microwave / Imager [SSM / I] F10 - F15).

These were based on U.S. Navy, Canadian and Danish aerial reconnaissance data and from retrievals from advanced very high resolution radiometer (AVHRR), passive microwave, and other satellite instruments

The primary sources of the post-1972 data are the hemispheric fields of sea - ice concentration from (1) the U.S. National Ice Center (NIC), whose weekly grids (derived primarily from satellite data) span the period 1972 - 1994, and (2) the satellite passive - microwave grids from the Scanning Multichannel Microwave Radiometer (SMMR) / Special Sensor Microwave / Imager (SSM / I) period, 1978 - 97 (Parkinson and othermicrowave grids from the Scanning Multichannel Microwave Radiometer (SMMR) / Special Sensor Microwave / Imager (SSM / I) period, 1978 - 97 (Parkinson and otherMicrowave Radiometer (SMMR) / Special Sensor Microwave / Imager (SSM / I) period, 1978 - 97 (Parkinson and otherMicrowave / Imager (SSM / I) period, 1978 - 97 (Parkinson and others, 1999).

Useful satellite data concerning sea ice began in late 1978 with the launch of NASA's Scanning Multichannel Microwave Radiometer (SMMR) satellite.

In the original configuration of NPOESS, the ocean surface vector wind data record established by QuikSCAT was to be replaced by passive microwave measurements of wind speed and direction by the polarimetric CMIS radiometer.

For example, the NASA Advanced Microwave Scanning Radiometer — Earth Observing System (AMSR - E) could fill in some missing data because it has a smaller pole hole than other satellites.

With MIS delayed until NPOESS C2, there is a need to continue the long (28 - year) climate data record of sea ice extent and concentration collected by passive microwave radiometers; continued scatterometer and altimeter measurements are also required.
