Super resolution maps of partial pressure $pC{O}_2$ between the ocean and the atmosphere

Participants : Hussein Yahia [correspondant], Véronique Garçon (laboratoire d'Etudes En Géophysique Et Océanographie Spatiales (legos)), Joël Sudre (laboratoire d'Etudes En Géophysique Et Océanographie Spatiales (legos)), Christoph Garbe (university Of Heidelberg), Christophe Maes (laboratoire d'Etudes En Géophysique Et Océanographie Spatiales (legos)), André Butz (karlsruhe Institute Of Technology (kit)), Boris Dewitte (laboratoire d'Etudes En Géophysique Et Océanographie Spatiales (legos)), Isabelle Dadou (université Paul Sabatier).

Multiresolution analysis computed on singularity exponents estimated from physical variables is used to produce submesoscale (pixel size: 4 kms) of partial pressures $pC{O}_2$ maps between the ocean and the atmosphere. Low resolution $pC{O}_2$ information coming from models and data is propagated across the scale of the specific multriresolution analysis to infer super resolution $pC{O}_2$ maps. Validation with model outputs and boat campaigns.
