RAMS Data Ingestion
Please contact RAMS Support for support of the RAMS software. The Data
Support Section does not support the RAMS software.
DSS knows that the following datasets may be used in RAMS:
NCEP ADP Observational data (DS353.1, DS353.4 and DS464.0).
NCEP Global Analyses "FNL" (DS082.0 and DS082.1.)
A user also informs us that RAMS includes software to convert GRIB to RALPH
format, so that it can be used, meaning that these datasets may be used:
NCEP Global Analyses "FNL" (DS083.0 and DS083.1.)
Based on our experience with RAMS users and Aster's advice, reading the data
from the NCAR Mass Storage System for subsequent use as RAMS input should
be done as follows:
1) The global grid data (from DS082.0 or DS083.0) should retain the COS-blocking,
so do (e.g.):
msread Y11491 /DSS/Y11491
2) The ADP data should NOT retain the COS-blocking, and no linefeed delimiting
should be done, so do (e.g.):
msread -fBI Y18933 /DSS/Y18933
NOTES:
1) While these procedures will yield files that are readable by the RAMS, they
are not universally readable by other software.
In particular, our own ADP software will not read an ADP file unless line-
feed delimiting is applied, which requires this (e.g.):
msread -fCH Y18933 /DSS/Y18933
2) When the only upper air data you need is radiosondes and pibals (ADPUPA),
use DS353.4 (List A) instead of DS353.1. Highly recommended because you
save the time involved with slogging through all the other higher volume
data types (AIRCFT, SATWND, AIRCAR) that are in each file of DS353.1.
For that matter, DS353.4 has both earlier and later data.
