The Integrated Climatic Model uses several file formats for modeling pavement temperature and moisture profiles. The format of these files is outlined below.
ICM files are generated by the hourly climatic database and contain all of the information needed to run the Integrated Climatic Model numerical engine.
StartDate(YYYYMMDD) –
EndDate(YYYYMMDD): The period for which this file contains data
for.

Hourly climatic database files contain information for a specific weather station. To add a weather station to those that are available within the ME-PDG, create a new *.hcd file. Assign a number unused in the station.dat file (described below). Add that number to the station.dat file list.
