摘要: |
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 available on many computer systems, but good calibration of the sensors to ensure accuracy of the products. Reliable calibration, formerly a chronic problem for some GEO imager channels, can be readily acquired using the more commonly operating, well-calibrated research satellites. Satellite-derived cloud and radiation products such as cloud phase or albedo have been available for a number of years from satellites devoted to climate studies but have been generated only sporadically from operational weather satellites. With improving forecast models and the ever-present need for air safety information, such products will be useful for model validation and assimilation and for diagnosing air-traffic hazards. |
