Weather App  Wildland fire weather observation calculation and archiving tool. This application allows quick calculation of RH, Fine Dead Fuel Moisture, and Probability of Ignition based on standard fire line weather observations. The app also provides means of archiving AND sharing those observations through other core Android functionality such as email, Dropbox, and Google Drive. Partial form submissions are allowed (and can be archived and shared), but entire form must be filled in to calculate FDFM and PIG. Bulk submission of multiple observations is now done on first page of app. This is a beta release. Free Android
