The AFGWC computer programs for the validation of surface, aircraft and upper air RAOB, PIBAL, and ROCOB reports are described. All reports received in standard codes from the DoD Automated Weather Network are subjected to a number of validation checks timeliness, gross error, internal consistency and deviation from a previous analysis or forecast. Failure to pass these checks can result in one of two actions one or two parameters may be discarded, or the entire report may be discarded. Validation of data from atmospheric soundings is discussed in detail. Examples are given to illustrate the methods used to determine whether upper air height andor temperature data are in error. Missing or garbled upper air temperature and height data for mandatory reporting levels are recomputed by solving a system of two simultaneous equations. Procedures to merge newly validated data with similar data validated earlier are briefly described. Author
