As of August 1, 2018, NRCS hosting of SHEF-encoded SNOTEL and SCAN data reports will be discontinued. 

NOAA will continue to provide SHEF-encoded data through its MADIS (Meteorological Assimilation Data Ingest System) data management and reporting system. Users can also retrieve data files from the NOAA MADIS data gateway.

Go to NOAA MADIS SNOTEL/SCAN Reports Directory

The NOAA MADIS server for SHEF-encoded SNOTEL and SCAN has a daily, hourly and monthly report directory. It has no edits directory because edits are no longer sent separately. Each hourly or daily report includes any edits made since the previous report.

Note that the new reports follow the same basic format with the following differences.

1. The MADIS hosted reports do not have an extra line feed after every line.
2. The MADIS hosted reports start the station id in the first column, not the second.

These differences were due to mistakes in the legacy NRCS system which the NOAA staff have corrected for the MADIS hosted reports.

NOTE: The new MADIS hosted reports have two defects that will require changes to users’ ingest programs until updated scripts are deployed to NOAA servers. 

• Daily report file issue: Daily summary values incorrectly show timestamp of 00 on the day following the observation.  Example shown:  The current data files show data as:

.B NRCS 20180721 PS DH05/TAIRM/PCIRM/SWIRM
APSC2  DT201807210000 / 50.540 / 11.5 / 0.0
.END

The data should appear like this:

.B NRCS 20180721 PS DH05/TAIRM/PCIRM/SWIRM
APSC2  DT201807202400 / 50.540 / 11.5 / 0.0
.END

• Hourly report file issue (does not impact most SNOTEL data – primarily impacts SCAN):  Hourly minimum and maximum air temperatures are incorrectly coded with TAIRMX and TAIRMN. They should be coded with TAIRMF and TAIRMD.

It is expected that these defects will be fixed prior to December 1, 2018.
