Abstract

Measurement of PRESSURE PROFILEs at limited number of synoptic stations are performed by the Radiosondes on a routine basis where this usually do not meet the need for numerical weather forecasting and there is need for more input data. Producing pressure values at different geopotential heights in the atmosphere is very important especially in the study of atmospheric circulation and weather forecasting. The data used in this research are: Radiosonde data, MODIS satellite images and surface pressure collected at synoptic stations. The method used is based on the hydrostatic hypothesis that is based on the assumption of small vertical movements in the air. The PRESSURE PROFILE is extracted from hydrostatic equation. This research consists of two parts, in the first part hydrostatic model has been evaluated for the stability index based on Radiosonde data, In the second part, PRESSURE PROFILE was calculated at different geopotential height using MODIS products of temperautre, moisture profiles and MODIS surface pressure. The average RMSE between Radiosonde measured profiles and MODIS data was 0.4 and 1 milibar, respectively. The results calculated through Hydrostatic models have a logical conformity with the one from the radiosonde measurements in both stable and unstable atmospheric conditions. The results show that by having surface pressure and temperature and moisture profile, one can calculate atmospheric pressure precisely in different altitudes using Hydrostatic model. The amount of uncertainties of the results of this method has been evaluated and is presented a seperate table.
