There are some situations that temperature will not show up on GC.
‧case 1 - No weather station or weather station doesn't have the weather information for current location and start time for an activity.
‧case 2 - The weather service is not accessible. Any processing of activities for weather data should be suspended (flagged) until service is once again available.
These activities should be processed once the Weather Service is available. Suggest checking every 5 minutes.
‧case 3 - Activity uploaded is older than 6 months so weather data is not available.
