River plume at the mouth of the Congo from EOS.

Land surface models usually use a land mask to differentiate between the land and the ocean, which are usually simulated by different models coupled together (e.g. JULES and NEMO in standard UK MetO prediction models). In order to be able to simulate coastal outflow (land -> sea) and intrusion (sea -> land), some kind of regular communication of data is required between these models.

On 4th February 2021 I organised a Zoom meeting with Simon and Eleanor to learn about the Coastal Impacts LTSM2 that is under discussion (see this ppt from June 2020 for LTSM2s). There will be a NOC-led LTSM2 in 2021 looking at sea->land intrusion.

When we know more about this call/project, I would like to call a science crossover meeting with NOC & PML.

More information:

• Dan Copsey's river outflow points are 1568 of the 1875 NEMO climatological runoff points (see the Ticket details of UM ticket #3405), i.e. more rivers than the 151 of COSCAT. Note that these are not calculationally linked to the river directions layer used by JULES and therefore cannot be assumed to be consistent with it in general.
