An Initial Study of Power Spectra from Satellite Imagery.

摘要

Air Force Global Weather Center (AFGWC) routinely generates a global cloud analysis called 3-D Nephanalysis (3-D Neph). At 15 levels in the atmosphere and for 25-mile square boxes, the cloud field is defined as clearly as possible with available data. All modes of data (surface, radiosonde, aircraft and satellite), are pre-processed and used prior to utilization by 3-D Neph by means of a decision tree process. This report reviews breifly the current approach at AFGWC, and the proposed method of processing increased amounts of data with a higher level of sophistication and greater efficiency. (Author)
