Sensitivity study of the radiative model into the retrieval code

Report on the implementation of the radiative model into the retrieval code and sensitivity studyASIMUT the radiative transfer code developed at BIRAIASB has been coupled to LIDORT to include the complete treatment of the scattering effects into the radiative transfer calculations The scattering module will be updated with the model developed in Task 33 Validation tests will be run to check the implementation and the improvement in simulating the role of clouds and dust This will be done on a subset of spectra recorded by SPICAMUV and NOMADUVIS both solar occultation and nadir selected to be representative of different dustclouds loading size and shape observed on Mars see Task 42Sensitivity studies will be performed by considering different sizes and shapes solar occultation or scattering properties nadir for the dust and cloud grains use of LIDORT and VLIDORT

Initial report on dust lifting and aggregation models

Initial report on dust lifting and aggregation modelsDust lifting depends on a number of parameters like grain size shear stress atmospheric pressure and gravity A model for lifting of sand and dust size grains will be worked out starting from an initial state of the art model modified by results of the projects Dust and sand lifted or suspended after the splash of a wind blown particle encounter other particles before the impact again or are resuspended for long time Especially dust grows to larger aggregates by hitandstick collisions The growth process is unknownThis initial report includes the description of the state of the art equations for lifting thresholds and aggregation properties

Space data sets selection

Reports on the selection of the different data setsThree different sets of data will be selected which correspond to 1 UVvisible spectra are highly sensitive to the radiative and microphysical properties of dust and clouds SPICAMUV NOMADUVIS Solarstellar occultation will be the best cases to test the sensitivity towards the size and shape impact because in such observations we can have direct access to the optical depth OD due to only dust and clouds While it is more complicated with nadir observations where the signal is a combination from surface reflection and scattering sometimes multiple by airborne aerosols that have similar spectral behaviour making them difficult to decorrelate Therefore nadir spectra are sensitive to optical depth SSA and phase function of aerosols These data will be further analysed to derive ozone Task 43 and dustclouds Task 44 The selection will be based on different criteria season latitudelongitude local solar time stormno storm conditions etc to build different subsets representative of different dustclouds conditions and characteristics 2 IR spectra of NOMAD are sensitive to water absorption which is very sensitive to temperature From this data set water vapor abundances will be retrieved Task 43 These spectra also allow the retrieval of CO2 In case of solar occultation temperature can be retrieved either from CO2 densities or directly from the spectra These quantities CO2 and temperature will help the comparison with model fields Task 54 The selection will be driven mostly by the spectral range sounded by the instrument which should contain features of H2O Another criterion which will be considered for both 1 and 2 data at least for NOMAD data is the simultaneity of the observations ie when both IR and UVIS channels are operating together This will allow us to derive a data set of ozone water dustclouds CO2 temperature obtained at the same time and same location probing the same portion of atmosphere 3 Data from other space missions will be also considered in this study They will first serve as validation for the new retrieval performed in Tasks 43 and 44 but also to increase the spacetime coverage needed to build representative climatologies Task 54 For nadir measurements recorded above Martian Rovers could be of particular interest as the aerosol optical depth could be constrained Spirit Opportunity and Curiosity Rovers perform direct measurements of the OD4 Data from groundbased observatories will be considered Members of BIRAIASB are involved in such observations through allocated time at ALMA SOFIA IRAM SUBARU for example Data obtained during previous and concurrent observation campaigns will be collected
