1 ENVISAT Validation using the DLR Falcon 20 Research Aircraft Overview over the Validation Activities Prepared by Andreas Fix, 04/11/02

The Falcon 20 D-CMET

ENVISAT Validation activities of the Falcon 2 Different Missions with different Payloads and Objectives:

SCIA-VALUE (SCIAMACHY Validation and Scientific Utilisation Experiment) Working Groups: University of Heidelberg, Germany: T. Wagner, K.-P. Heue, U. Platt, University of Bremen, Germany: H. Küllmann, A. Kleinböhl, K. Künzi, A. Richter, M. Bruns, P. Wang, J.P. Burrows German Aerospace Center (DLR): A. Fix, G. Ehret Objectives: Validation of SCIAMACHY level-2 data products: O 3, N 2 O, NO 2, BrO, ClO, H 2 O, OClO, and cloud and aerosol optical properties

SCIA-VALUE Falcon Payload

SCIA-VALUE: Falcon Payload Falcon 20 equipped with the three remote sensing instruments ASUR, AMAXDOAS, and OLEX for air-borne validation of SCIAMACHY data products O 3, N 2 O, NO 2, BrO, ClO, H 2 O, OClO, and cloud and aerosol optical properties

2 Main Campaigns: (~ 100 flight hours) September 2002 successfully performed Feb/Mar 2003 (planned) SCIA-VALUE: Flight Tracks

MIPAS-VAL Objectives: -The measurement of water vapour and aerosol profiles using the airborne H2O-DIAL of DLR as the core instrument and the comparison of these data to the respective MIPAS Level 2-products. -Intercomparison with the remote and in-situ GEOPHYSIKA instruments measuring water vapour and aerosol (i.e. MIPAS-STR,SAFIRE-A, FISH, FLASH, MAL, MAS, FSSP, ABLE) -Measurement of small-scale structures in the tropopause region, the comparison of these results with the ENVISAT products and model results of climate and climate-chemistry models. Campaign: -Joint campaign with the GEOPHYSIKA mid-latitude validation activities (Forli’, Italy (October 2002))

MIPAS-VAL: Falcon Payload all instruments operated by DLR (PI: Andreas Fix)

Summary of MIPAS overpasses during the Forli‘ 2002 campaign (14-28/10/02) 8 Falcon Flights total (25.5 h) 4 Flights co-ordinated with GEOPHYSIKA )* 4 flights at daylight 4 flights at night-time

Summary 2 Falcon Missions: SCIA-VALUE  2 main measurement campaigns (~50 flight hours each)  First campaign succesfully performed (Sep. 2002)  Second campaign scheduled for Feb/Mar 2003  No need to change flight plan or instrumentation MIPAS-VAL  Validation campaign (Forli‘ 2002, ~25 flight hours) successfully performed  No further campaign activity within this mission
