Fire Weather Calculator
By National Center for Landscape Fire Analysis
This app is only available on the App Store for iOS devices.
Wildland fire weather observation calculation and archiving tool.
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 email.
Partial form submissions are allowed (and can be archived and shared), but entire form must be filled in to calculate FDFM and PIG.
This looks like a handy tool for recording weather observations. Conveniently calculates elevation, lat/long and option of adding photo. It would be more helpful with a few (simple?) modifications: option to enter RH directly rather than wet bulb; ability to bundle multiple observations to one incident (and view those results in a table - maybe by turning phone sideways); and include "flat" with aspect.
