Rule-Based Systems for Visibility Forecasts

“…The CSI and skill scores for the three locations are listed in Table 1, based on statistics provided in GEOMET's final report. 2 The results presented in Table 2 were derived from two separate sources: real-time operation by Seymour-Johnson forecasters and operation by GL researchers using archived data. Only one forecast per day was considered, generally at 2000 hours local time, with a forecast period extending to the following morning.…”

“…GEOMET noted this situation in its report. 2 The manual form of data entry was reluctantly adopted, because the costs and complications involved in an Secondly, forecasters don't always need or want to consider the dewpoint spread at all surrounding stations. Instead, they are more interested in a more narrowly defined window of upwind stations.…”
