Bug report: GMAO_FP ancillary data, inconsistent pressure units

Bug report
Surface pressure is in millibars/hectopascals for previous NASA ancillary data sets, but in GMAO GEOS-5 FP-IT ancillary data files, the pressure unit is in pascals (1 mbar = 1 hPa = 100 Pa). Polymer v.4.16 doesn't do the conversion to millibars while it loads GMAO_FP ancillary data, which leads to 100-fold too high atmospheric pressures and then gives index overflow in the LUT table lookup.
