Abstract:

Conventional-report Nephanalysis is the construction of large-scale representations of cloud distribution by the use of surface-based observations. It is complementary - and perhaps subsidiary - to nephanalysis by the interpretation of satellite imagery, but can serve a vital function by providing reference fields against which the results of satellite-data processing algorithms may be evaluated. In this document is described an implementation of AFGWCs conventional-report processor which was developed at AFGL for use on the AFGL Interactive Meteorological System. Two sets of conventional reports from the canonical case-study days 82162 Summer 2100 UT and 85010 Winter 0000 UT were processed, for comparison against AFGWCs nephanalysis, AFGLs satellite-data nephanalysis, and cloud truth.
