Data assimilation: The Schrödinger perspective [PDF]

Acta Numerica, 2019
Data assimilation addresses the general problem of how to combine model-based predictions with partial and noisy observations of the process in an optimal manner. This survey focuses on sequential data assimilation techniques using probabilistic particle-based algorithms.

ASSIMILATION OF MARTIAN OZONE [PDF]

, 2013
Observations of atmospheric ozone on Mars can be used to develop the representation of trace gas transport, sources and sinks within global circulation models and constrain middle atmosphere wind speeds which are not observed directly.

Assimilating the Martian water cycle [PDF]

, 2012
Water ice clouds have been shown to alter the thermal structure of the Martian atmosphere. Here we discuss the assimilation of total column water vapour and dust optical depth data from the Thermal Emission Spectrometer (TES) into the UK/LMD MGCM, and ...
