Jonah works on monitoring and developing the OSTIA analysis and the GMPE system.
Jonah is responsible for the maintenance and development of the OSTIA SST and sea-ice product. The OSTIA team monitor and validate satellite and in-situ SST observations and the OSTIA analysis fields on a daily basis. The full OSTIA product suite is freely available to external users through the MyOcean project.
Jonah has worked on the production of OSTIA long-term reanalysis products, most recently the ESA SST CCI analysis. This high resolution SST and sea-ice reanalysis included recent updates to the OSTIA background error covariance's that resulted in significant accuracy and feature resolution improvements. Jonah is currently working on transitioning the OSTIA system to use the NEMOVAR assimilation code.
Jonah has been a member of the Ocean Forecasting Development team since April 2012 when the OSTIA R&D moved from the Marine Data Assimilation team which he joined in 2009. Before this Jonah worked on a 48-week placement in the Met Office Hadley Centre in the Climate, Cryosphere and Oceans team on projects including using the pattern scaling technique to add spatial information to climate predictions from a simple climate model.
