This new product, however, exploits direct broadcast (DB) capability from several satellites in low Earth orbit that
make microwave measurements over the continental United States and Alaska.

And
measurements of cosmological parameters — the fraction of dark energy and matter, for example — are generally consistent, whether they are
made using the light from galaxies or the cosmic
microwave background.
In contrast, the Scripps team opted to directly correlate albedo
measurements made by NASA's CERES instrument data with observations of sea ice extent
made by the Special Sensor
Microwave Imager (SSM / I) radiometers aboard Defense Meteorological Satellite Program satellites.
«However, the difficulty was still very daunting, and Hosang [Yoon]
made it all possible by performing very fine and subtle
microwave engineering and
measurements — a formidable piece of experimentation.»
Since 2003, WMAP researchers have
made more precise energy
measurements of the
microwaves that allow them to look farther back in time.
The SPT is designed to conduct low - noise, high - resolution surveys of the sky at millimeter (mm) and submillimeter (submm) wavelengths, with the particular design goal of
making ultra-sensitive
measurements of the cosmic
microwave background (CMB).
In this lecture, George Efstathiou will describe how recent
measurements of the cosmic
microwave background radiation
made with the Planck Satellite can be used to answer these questions and to elucidate what happened within 10 - 35 seconds of the creation of our Universe.
All these sensors
make measurements at critical frequencies at and above 85 gigahertz (GHz); sensors measure
microwave emissions at 183 GHz, the signature frequency band emitted by water vapor,
making it feasible to detect frozen hydrometeors (snow, ice, and the like) in the atmosphere.
However, highly accurate
measurements made by satellites, like the Wilkinson
Microwave Anisotropy Probe (WMAP)[2], have corroborated that the deep space has a temperature and, additionally, that it is not an absolutely -LSB-...]
The animation was
made with
measurements taken by the Advanced
Microwave Scanning Radiometer — EOS (AMSR - E) on NASA's Aqua satellite between March 7 and September 9.
QuikSCAT
measurements are also limited to a spatial resolution of 12.5 km and are not routinely
made closer than about 30 km from land.26 Many in the
microwave breakout group argued that high priority should be given to a sustained, more capable, next - generation scatterometer program that can meet these requirements while at the same time continuing the ocean surface vector winds CDR established by QuikSCAT.
«Satellites are not a thermometer in space, they're not
making direct
measurements of atmospheric temperature, they're measuring the
microwave emissions from oxygen molecules,» Santer said.
