The ATLAS/ICESat-2 L3B Daily and Monthly Gridded Sea Ice Freeboard (ATL20), Versions 2 and 3 and the ATLAS/ICESat-2 L3B Daily and Monthly Gridded Polar Sea Surface Height Anomaly (ATL21), Versions 1 and 2 data sets, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), contain an error in the grid_lon variable. All values within the grid_lon variable are off by 180° longitude due to an incorrect conversion from 0° to 360° to -180° to 180°. The data producers are aware of the error and are working on a fix, which will be included in the next version of each data set. In the interim, adding 180° to grid_lon values will convert back to the 0° to 360° convention. The spatial variables grid_x and grid_y are not affected.
