Comparison of Megha-Tropiques derived Humidity with those from Ground Based Microwave Radiometer:
The comparison of Megha-Tropiques SAPHIR (MTS) derived humidity is important for the effective utilisation of MTS RH for addressing scientific issues. Therefore, a validation has been made by comparing the MTS derived layer averaged Relative Humidity (RH (%)) with that of the ground based multi-frequency Microwave Radiometer Profiler (MRP), over Thiruvananthapuram. The comparison between the MRP and the MTS derived RH has been made in five different altitudinal layers (centred at 0.75, 2.25, 4, 6.25 and 9.2 km range) strictly under clear sky condition. This activity has been carried out with the collocated MRP data.
