SNOTEL GOES Manual Revision 2b - February 17, 2011 page 2 of 10

Micro Specialties, Inc. Wasilla, Alaska

Application Overview

msiDCSDecodeR2, provided by Micro Specialties, Inc (MSI), is designed to automate

the retrieval of GOES data reports from the National Environmental Satellite Data

Information System (NESDIS). These reports are presumed to have been generated by

a Campbell Scientific (CSI) data logger, and communicated through the GOES system

via a CSI TX412 data modem, or via a MicroComm GTX data modem. The application

can be configured to collect data from any number of GOES data platforms, and will

generate SNOTEL-compatible data messages intended to be automatically ingested by

SNOTEL. Data messages received from GOES, are automatically processed and

appended to an output text file named mbdata.txt. An external, cron-timed batch

process should be provided by NWCC, that will execute msiDCSdecode and feed the

content of mbdata.txt into the SNOTEL system. The batch process should rename

mbdata.txt to avoid having the application write to it while the batch is running, then

delete it when its content has been ingested into SNOTEL, as this application will never

delete or shrink mbdata.txt.

New Features and Revisions in Revision 2a 2/9/2010

 Decodes all GTX sensor labels

 Recognizes sensor values generated internal to the GTX such as the 'Clock',

'Battery', and values from the equation editor.

 Understands GTX min/max/avg (NXG) flags

 Will decode multiple values from a single GTX TPL Data Parameter entry

based on the 'Value Count' of that parameter.Allows more flexibility in site

group definitions.

 Keeps track of successful data retrieval events to help prevent data gaps.

 Exports most GOES procedures to new GOES python module.

 New command line option to “fresh start” retrieval history.

New Features and Revisions in Revision 2b - 2/16/2011

 ddsClient now logs only retrieve dates more recent than the last entry in the

log. This is intended to remove duplicate entries in the log.

 Sorts the data records (mbdata.txt) by the data time stamp.

 ddsClient now restricts attempted data retrieval to within 30 days of the

current date. Dates in the future are not allowed.

 ddsClient now attempts to get data from the primary LRGS server, but will

switch to the backup server if the primary does not respond. The ddsClient

module now defines the IPs for the primary and backup LRGS servers.

 Provides a command line option to use a specified LRGS (host) IP.
