[RegCNET] problem to get ICBC from EH5OM

Dear all,

My previous problem seems to be solved by using lon0=0, lon1=358.125, 
lat0=-89.0625,lat1=89.0625.
However, we got another problem in running the regcm.x, with the 
following warning and error message about rh:
...
26           1 -4.956840604696050E-006   RH WARNING !!!!!
26           1 -4.956840604696050E-006   RH WARNING !!!!!
26           1 -4.956840604696050E-006   RH WARNING !!!!!
26           1 -4.956840604696050E-006   RH WARNING !!!!!
     at day =    0.0851, ktau =         50 :  1st, 2nd time deriv of ps 
=  NaN         NaN        ,  no. of points w/convection =       0

So maybe something is still not quite right in the ICBC. Anyone has a clue?
What is the difference of FNgA2/'EHgA2' / and FN_A2/'EH_A2'/ in lines 
1234-1235 in the original ICBC.f ?
   1234 cjq      DATA    FNgRF/'EHgRF'/  ,FNgA2/'EHgA2'/
   1235 cjq      DATA    FN_RF/'EH_RF'/  ,FN_A2/'EH_A2'/
   1236       DATA    FNgRF/'EHgRF'/  ,FNgA2/'EgA1B'/
   1237       DATA    FN_RF/'EH_RF'/  ,FN_A2/'EHgPS'/
where EgA1B... and EHgPS ... are the EH5OM data downloaded from the ICTP 
site.

thanks,
Joshua
