This document describes predefined element table in NuSDaS.

Symbol ? in table indicates "undefined" or "unknown to the author".
GRIB1 field shows corresponding GRIB (edition 1) parameter indicator. This can be used in conversion to GRIB 1. Asterisk '*' before the code indicates that the NuSDaS element name is NOT used in case of conversion from GRIB 1, generally because the units is different from that in GRIB.
GRIB parameter indicator more than 127 is local assignment of Japan Meteorological Agency.
When you are handling data integrated over time (i.e. the time attribute of type2 is AV), multiply s to the units in this table.
Element names beginning with underline character '_' are used when the time attribute of type2 is SV, which is properly used for dataset of snapshot data. They indicate that the element is time integration (or maybe average). Refer v1.0 SUBC TDIF record to obtain information on integration time. In case of such time-integrated data, you have also to multiply s to the units in this table.
