Primary Design GoalPrimary Design Goal
• Add GOES data modems to the Add GOES data modems to the SNOTEL operational frameworkSNOTEL operational framework
Design RequirementsDesign Requirements• Automate retrieval of GOES data Automate retrieval of GOES data
from NESDISfrom NESDIS• Automatically import GOES data to Automatically import GOES data to
SNOTEL in MBD message formatSNOTEL in MBD message format• Accommodate popular GOES modem Accommodate popular GOES modem
modelsmodels• Do not impact SNOTEL structureDo not impact SNOTEL structure• Eliminate recurring costsEliminate recurring costs• Should be OS portableShould be OS portable

• Retrieve data message context from Retrieve data message context from NESDISNESDIS
• Associate GOES ID with SNOTEL IDAssociate GOES ID with SNOTEL ID
• Decode and translate data message Decode and translate data message context to FP2 parameter format for each context to FP2 parameter format for each sensor valuesensor value
• Generate data messages in MBD format for Generate data messages in MBD format for direct import to SNOTELdirect import to SNOTEL
• Generate and save GOES RMP messagesGenerate and save GOES RMP messages
