Document issues with our mapping file generation tool chain at high resolution. Instructions on using MBtempest: Offline remapping workflow with mbtempest
Status
For PG2 grids, we currently do not have an acceptable solution that would allow us to run at 3km (ne1024).
TempestRemap: Highres maps have poor conservation and consistency (1e-6).
MBTempestRemap: NaN’s or too large weights. conservation/consistency errors similar to TR.
ESMF: For PG2 grids, we can rely on ESMF ‘aave’ maps, which are good up to ne512pg2. Unacceptable at ne1024pg2
Analysis Mapping files
Mapping files are needed for remapping native grid output to lat/lon grids for conventional analysis tools. Often exact conservation is not required making TR’s integrated bilinear a good option: it’s accurate, has built in downscaling and is monotone so it wont introduce spurious oscillations making it good for plotting.
