The Air Force Global Weather Central (AFGWC) hosted a conference on objective data analysis 2–4 October 1985. This was a continuation in a series of conferences on data analysis. Participants included both operational meteorologists and research meteorologists from various government's numerical weather prediction (NWP) facilities.

The conference consisted of each participating facility reviewing their current status and future plans. Individual topics were then presented concerning data analysis, followed by small group discussions on meteorological and computational aspects of objective data analysis.

Various conclusions were developed during the conference: 1) Optimal interpolation is the analysis method most commonly used at NWP facilities and is favored for its ability to assimilate data from many different observing platforms. 2) Promising work continues with the insertion of new data into the analysis model. 3) The fundamental difference between most analyses is the difference in the imposed quality control. 4) Further improvements in data assimilation are possible if archival procedures are performed to gather covariance statistics.
