Fire weather calculator

Wildland fire weather observation calculation and archiving tool.

*** The new version of the Fire Weather Calculator includes ANONYMOUS sharing of weather observations with researchers at the University of Montana. The anonymous observations will be used to support research in weather prediction, analysis, and content display. Data shared with UM will only contain data fields from the app (photos are excluded) and a device ID (to differentiate between users). No personal information is shared. We ask that you "opt-in" to anonymous sharing in order to support these research projects. Anonymous sharing can be changed any time in the "Settings" page of the app. Thank you! ***

This application allows quick calculation of RH, Fine Dead Fuel Moisture (FDFM), and Probability of Ignition (PIG) 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 are now done on first page of app.

This is a beta release. Please forward questions to email listed below.

Developed by The National Center for Landscape Fire Analysis, College of Forestry and Conservation, University of Montana.
