These mapping files are mostly used to generate initial conditions. Remapping the cam.i file from a spunup NE30 simulation will generate a reasonably well spunup initial condition file for higher resolutions.
TR “mono” (with code fixes from )
ne30np4 → ne256np4
Tempest fixes from : weights are good. row sum error 1.3e-15, conservation error: 5e-14.
Status: GOOD
ne30np4->ne512np4
Status: GOOD
MBTR “mono”
ne30np4->ne256np4
--monotonic 1: mapping weights have NaNs
--monotonic 3 --noconserve (“intbilin” option) weights are bad, max = 2.5
Status: NOT USABLE
ESMF “bilin”
ne30np4->ne256np4
weights between [0,1]. row sum error 2.2e-16. conservation error: 3.4e-1 (bilin is not conservative)
mapping file frac_a=0 (BUG?), but frac_b=1
Status: GOOD
ne120np4->ne512np4
Status: GOOD
ne120np4->ne1024np4
10M out of 120M weights are bad, >> 1.0. max row sum = 5.0
Status: NOT USABLE
ESMF “aave”
We dont consider these maps. We are trying to move away from these maps since they require the “dual grid”, which is difficult to produce and unnatural for GLL grids.
