TEMPO Algorithms

Introduction 5/23/132 We will begin with the default launch data products, which are the gases O 3, H 2 CO, C 2 H 2 O 2, NO 2, and SO 2, and aerosols, clouds, and UVB. By default, we will reproduce OMI products as fully as possible. We can then branch out into improved and additional products. For those algorithms with particularly strong OMI heritage, producing the DLPs may be a hybrid process, since operational OMI code can morph into operational TEMPO code. In the SAO case of least-squares fitting, to be applied to H 2 CO, C 2 H 2 O 2, NO 2, and SO 2 (and probably some additional products) we will start with our OMI code, simplify it, and add the functionalities to, as options, (1) do DOAS fitting (in but never tested) and (2) to use wavelength-dependent AMFs. NO 2 adjustment for the stratosphere will be done in a collaboration among SAO, GSFC, and Dalhousie U.

Approach 5/23/133 Ground systems are at SAO in Cambridge: 1.Commanding processing processing 4.Higher level products (AQ maps) 5.Apps for NRT products Archiving and distribution at SAO plus final archive at a NASA-specified DAAC

Default launch data products 5/23/134 1.TOMS-type O 3, in collaboration with GSFC 2.eXceL O 3 done by SAO in collaboration with RT Solutions, for scenes limited by computational power (but maybe the entire FOR at 8×9 km 2 ) 3.NO 2 fitting by SAO, stratospheric correction in collaboration with GSFC, Dalhousie 4.SO 2 fitting by SAO in collaboration with GSFC 5.H 2 CO fitting by SAO 6.C 2 H 2 O 2 fitting by SAO 7.Clouds as in GSFC OMI clouds 8.Aerosols as in GSFC OMI aerosols 9.UVB as in OMI GSFC/FMI 10.AQ indicators, from previous products, in collaboration with EPA and Dalhousie. Includes NRT products, apps
