French research activities dedicated to the calibration/validation of Earth-CARE data were grouped according to the approach followed to obtain the validation data:
| ACTRIS-FR | Ground-based measurements from French atmospheric stations (P. Goloub, LOA) |
| VECARE, SPACECARE | Ground-based field campaigns Arctic (VECARE, G. Ancellet, LATMOS) and Antarctic (SPACECARE, C. Genthon, LMD) |
| MORECALVAL | Mobile and airborne field campaigns (J. Delanoe, LATMOS) |
| BAIVEC | Balloons (J.-B. Renard, LPC2E) |
| STACCATO, MPP | Monitoring of signal data quality through statistical analysis of ATLID (STACCATO, H. Chepfer, LMD) and MSI (MPP, N. Scott, LMD) data |
