Hindcast and four-ensemble forecast of Pan-arctic Ice-Ocean Modeling and Assimilation System (PIOMAS) with 12-category sea ice thickness distribution (ITD) and floe size distribution (FSD)

PIOMAS has varying spatial resolutions for the Arctic Ocean and adjacent seas

Hindcast period available: 1979-2024, 4-ensemble forecast period:
06/01-8/26/2024 

Hindcast atmospheric forcing: NCEP Climate Forecast System (CFS) hindcast
forcing
Forecast atmospheric forcing: NCEP Climate Forecast System (CFS) forecast
forcing (4 ensembles)

Data include: hindcast monthly mean sea ice thickness in m (heff.H), concentration in area fraction (area.H), and velocity in m/s (icevel.H) in directory hindcast; 4-ensemble forecast daily sea ice thickness (hiday.H), concentration in area fraction (aiday.H), and velocity in m/s (uiday.H) in directories forecast_ensemble1, forecast_ensemble2, forecast_ensemble3, and forecast_ensemble4.

Data files are in binary format

A Fortran code is provided to show how to read relevant binary files: read_360_120.f

Relevant model grid info files are provided such as latitude and longitude at
each model grid cell, and model domain mask

The PIOMAS data are generated with the support of the NASA Cryosphere Program (80NSSC20K1253), the Office of Naval Research (N00014-22-1-2346), and the NSF Office of Polar Programs (NNA-1927785).
