Service Description: In the Fire Information and Resource System (FIRES), “Green Up Stages” are divided into four categories: Snow; Grass/Shrub; Deciduous; and Coniferous. Snow stages are reported as: SOG (Snow on Ground) if 75% or greater of the surrounding area is covered in snow; SPG (Snow Patches on Ground); or SGN (Snow Gone) if 25% or less of the surrounding area is covered in snow. These stages are collected and reported in FIRES for each weather station as they occur throughout the fire season. The data is automatically extracted and imported into AWARE daily at 13:45h. These Green Up Stages can be displayed independently to show snow on ground throughout the province on a daily basis. Inverse distance weighting is used to interpret values between weather stations. A snow mask is applied to weather stations that are reported as SOG or SPG when interpolating fire weather codes and indices between stations. Fire Weather Index (FWI) System start-up codes are calculated for weather stations that are reported SGN only; and consequently only those stations generate fire weather codes and indices.
