Cloud properties were retrieved by applying the Clouds and Earth's Radiant Energy System (CERES) project Edition-2 algorithms to 3.5 years of Tropical Rainfall Measuring Mission Visible and Infrared Scanner data and 5.5 and 8 years of MODerate Resolution Imaging Spectroradiometer (MODIS) data from Aqua and Terra, respectively. The cloud products are(More)
New sensors and retrieval algorithms have facilitated the development of more quantitative uses for geostationary (GEO) satellite data in weather and climate. For weather applications such as data assimilation or air safety, near real-time processing is needed to produce datasets in a timely fashion. It requires not only fast data throughput, readily(More)
Atmospheric models rely on high-accuracy, high-resolution initial radiometric and surface conditions for better short-term meteorological forecasts, as well as improved evaluation of global climate models. Remote sensing of the Earth’s energy budget, particularly with instruments flown on geostationary satellites, allows for near-real-time evaluation of(More)
Imagers on many of the current and future operational meteorological satellites in geostationary Earth orbit (GEO) and lower Earth orbit (LEO) have enough spectral channels to derive cloud microphysical properties useful for a variety of applications. The products include cloud amount, phase, optical depth, temperature, height and pressure, thickness,(More)
Contrails, like natural cirrus clouds, can cause a warming of the Earth-atmospheric system by absorbing longwave radiation from the surface and lower troposphere and radiating additional radiation back to the surface. They can also produce some cooling of the surface during the daytime by reflecting some sunlight back to space. Recently, Minnis et al.(More)
Narrow spectral bands in the thermal infrared (IR) atmospheric window (10-12 μm) are commonly used to derive cloud top heights from passive satellite imagers (Minnis et al., 1998). When the field-of-view (FOV) of a satellite imager, such as the Moderate Resolution Imaging Spectroradiometer (MODIS), is completely cloud-filled, the observed brightness(More)
Satellite data have long been used for determining the extent of cloud cover and for estimating the properties at the cloud tops. The derived properties can also be used to estimate aircraft icing potential to improve the safety of air traffic in the region. Currently, cloud properties and icing potential are derived in nearreal time over the United States(More)
