EUMETSAT IASI Level 2 Temperature and Humidity Profiles

EUMETSAT IASI Level 2 Temperature and Humidity Profiles are Level 2 atmospheric sounding products distributed by EUMETSAT for Metop IASI profile retrieval use.^[1][2] The product provides temperature and humidity profile outputs derived from Metop IASI, AMSU-A, and MHS measurements.^[1][2] Access is through EUMETSAT data services under EUMETSAT access terms, with the listed product portal serving the Data Store entry point.^[1] The product is available in EPS native and BUFR formats for orbital deployment-context workflows.^[1] It fits operational atmospheric sounding, numerical weather prediction input and monitoring, and profile retrieval workflows that can use infrared sounding combined with microwave measurements.^[1][2] Practical use depends on retrieval conditions: IASI is an infrared sounding product, so cloud conditions affect profile utility, and the listed EARS product combines IASI with microwave sounder measurements.^[2]
