These algorithms incorporate high-resolution sensor data from multiple military and civilian satellites, polar and geostationary, into a real-time cloud analysis model and apply multispectral cloud analysis techniques that improve the detection and specification of clouds, especially cirrus and low clouds. The SERCAA algorithms consist of a number of processes involved in integrating cloud analyses from multiple satellite platforms into a single cloud analysis product. The steps required to process the raw sensor data, collected from each of the satellite platforms, into each of the individual cloud analysis products include total cloud algorithms for DMSP, AVHRR, and geostationary platforms, cloud layer and type algorithms, and an analysis integration algorithm. The SERCAA data products for the CDFS II baseline include: total cloud cover fraction, number of cloud layers (up to four floating layers), cloud layer coverage fraction, cloud type, cloud height, and analysis confidence level. 收起
