CMA is the Chinese Meterological Administration.  Unfortunately, all the 
documentation I have is in Chinese. ;-) Here is a rough translation:

Year, Month, Day, Hour, NumObs
   st_num lat(deg) lon(deg) alt(m)
   pr(hPa) hh(m) temp(degC) td(degC) wind_d(deg) wind_s(m/s)

missing value is 99999.90

I've attached a sample CMA file. 

As you found out, we do support the ESRL netCDF format.  I'll look at the text 
format to see what it would take to support that.
