Description:The impact of vertical temperature profile radiometer (VTPR) data from the NOAA-2 satellite is examined by comparing numerical analyses and forecasts made with and without these data. VTPR soundings are part of the normal data base for the operational analyses at the National Meteorological Center (NMC). For 30 days in March and April 1973, parallel analyses were produced using the same analysis and forecast codes but with VTPR soundings excluded from the data base for the parallel mode. Forecasts to 48-hr were made from parallel-mode analyses on 9 of these days. Comparisons between these forecasts and the corresponding operational forecasts show at best a very slight improvement in forecast skill from use of VTPR soundings. Differences between analyses produced with and without the satellite retrievals are, in general, quite small. This appears to be due, at least in part, to a lack of retrievals from the meteorologically active baroclinic zones.
