Historic Update Information:

Fire15_1 was released June 9th, 2016. The ALARM_DATE and CONT_DATE fields have been changed from STRING fields to DATE fields. In the many cases where only the year of a fire existed (ex. 19170000) the tool couldn't process the data and the entry is NULL. In those cases, the year can be found in the YEAR field.

Fire14_1 was released in May, 2014. After release, the NPS supplied corretions for 14 wildfires and 67 prescribed burns. The corrected data was posted to FRAP's data download page as fire14_1 in late May.

Fire 14_2 was released in July, 2015 to reflect that changes had been made to the original release in late May. Version 14_1 from late May is an exact copy of version 14_2 released in July.
