Evaluating IASI profiles at the ESSL Test-bed and for selected cases


Pieter Groenemeijer reports of the tests ESSL has undertaken to check the usability of ISAI L2 temperature and humidity profiles in storm forecasting.

Length: 44 minutes.


ESSL studied the use of retrieved temperature and humidity profiles available from the Infrared Atmospheric Sounding Interferometer (IASI) instrument on the polar-orbiting Metop satellites for storm forecasting during the 2019 Testbed and for a number of cases. Parameters relevant to convective storm prediction such as CAPE, CIN and humidity at various levels were computed and a direct visual comparison between the satellite-derived and NWP-modelled profiles was made possible. We present the main conclusions of this study, addressing the usability of the products, preferred derived parameters and observed limitations.
