Estimated Temperature Corrections for the Menaka-II Meteorological Rocket Payload

Abstract

The temperature as indicated by the meteorological payload is not the real temperature of the environment. The indicated temperature has to be corrected to get the exact temperature at the particular height. There are various corrections due to the thermistor inertia, its mounting position, descent rate of the parachute and the effect of solar radiation at each height. All these corrections are calculated at intervals of 10 km and the order of correction is calculated in terms of degrees Centigrade for the meteorological payload to be launched with an Indian Rocket Menaka-II. The temperature correction varies from 0·3°C at the ground to 10-15°C at 80 km.
