Every paper I have published over the last 5 years has relied on these sea ice data sets. This is a real blow

Awful. More horrible science news

"The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) learned yesterday that the Department of Defense (DoD) will stop processing & delivering the Special Sensor Microwave Imager/Sounder (SSMIS) data no later than 30 June 2025."

Screenshot from NSIDC that says: "Dear Colleague:

The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) learned yesterday that the Department of Defense (DoD) will stop processing and delivering the Special Sensor Microwave Imager/Sounder (SSMIS) data no later than 30 June 2025. The SSMIS data are used as input for the following NSIDC DAAC-produced data sets, which will therefore stop processing no later than 30 June 2025:"

Also, if you're interested in how ML can be incorporated into large-scale sea ice model Fortran code, check out the Github repo! github.com/m2lines/SIS2...

We also investigate the importance of exposing ML models to coupled feedbacks before implementation, the. impacts of coupled model biases on ML generalization, and forecasting extreme events

Will Gregory @willjgregory.bsky.social · May 28

We have a new @m2lines.bsky.social pre-print which shows how machine learning can be used for state-dependent bias correction to improve global coupled climate model sea ice forecasts - take a look!

So sorry to hear this Zack. I hope you're ok

Will Gregory @willjgregory.bsky.social · Feb 25

i just checked scholar yesterday to see if this paper was out yet! Great job to Harry!

Data-Driven Science: Developments in Machine Learning Subgrid-Scale Parameterizations and in Reanalyses Across Earth System Modeling I Oral

Subgrid-scale (SGS) parameterizations estimate effects of unresolved processes without modeling them directly and are often a large source of uncertainty in Earth system models (ESMs). The need to imp...
