NMC TDL Manually Digitized Radar, November 1973 to September 1977

Manually-digitized radar data have been collected from teletype reports and archived in the Model Output Statistics (MOS) predictand tape format since November 1973. These data are intended for both general and severe thunderstorm prediction using MOS which relate the radar data to large-scale predictors from operational numerical models. This dataset contains manually-digitized radar data for the period from 1 November 1973 to 5 September 1977 on a 26-by-33 grid covering the United States. This grid is a subset of NMC's 47-by-51 Northern Hemisphere polar-stereographic octagonal grid.
