Data for "A space-time conditional intensity model for evaluating a wildfire hazard index" by Peng, Schoenberg, and Woods

Wildfire data

fires.txt [23K] -- Wildfire dates, locations, and areas burned for Los Angeles County, 1976--2000. Fires smaller than 10 acres were excluded and the locations are the x-y coordinates of the centroids of the polygons defining the burn area. The format of the table is as follows:

date

the date of ignition in year-month-day format (YYYY-MM-DD)

xcent, ycent

centroid coordinates in

• Coordinate system: California State Plane Zone V
• Datum: NAD 83
• Units: Feet

area

burn area in acres

The locations are the x-y coordinates of the centroids of the polygons defining the burn area. After downloading the file, the data can be read into R (version 2.0.0 or higher) with the following command:

fires <- read.table("fires.txt", header = TRUE, colClasses = c("Date", rep("numeric", 3)))

fires.rda [12K] -- Same wildfire data as above except stored as a compressed R workspace file. After downloading the file, the data can be loaded directly into R using the load() function.

Burning Index (BI) data

BIdata.txt [1.3M] -- Burning Index (BI) daily data for 8 weather stations in Los Angeles County. The table has 3 columns:

burnindex

The Burning Index value as computed by the FireFamily Plus software (the BI has no units). Note: The values provided here were computed using version 2.02 of the software.

StationID

An ID number for the weather station with which the BI value is associated.

date

The date of the observation in year-month-day format (YYYY-MM-DD).

A value of NA indicates missing data. After downloading the file, the data can be read into R (version 2.0.0 or higher) with the following command:

bidata <- read.table("BIdata.txt", header = TRUE, colClasses = c("numeric", "factor", "Date"))

BIdata.rda [240K] -- Same BI data as above except stored as a compressed R workspace file.

• station-locations.txt -- x-y coordinates of weather station locations for Los Angeles County.
