• change the colors of the fires/thermal anomalies and
• change the fire pixel size
• show only day or night detections
• color code fires by Fire Radiative Power (FRP), Confidence or Time Since Detection

CHANGE FIRE COLOR BY INSTRUMENT

The default color for the MODIS and VIIRS thermal anomalies is red. There are times when it is useful to be able to distinguish between instruments (MODIS/VIIRS) or day/night detections. To do this Select ADVANCED MODE  MODE in the Layer List on the right of the map (see image below) 

Select the "+" icon next to the fire detections you want to change.

...

This step can be repeated for other fire detection categories.

CHANGE FIRE PIXEL SIZE

The fire pixel size defaults to the optimal display for the zoom level. When zoomed right ininto the highest zoom levels, MODIS pixels maintain a size of approximately 1km and VIIRS approximately 375m

...

To change the pixel size, make sure ADVANCED MODIS is MODE is selected (as shown above). Click the "+" icon and then click the drop down arrow next to the word "Auto"

...

Adjust the pixel size from the drop down list  

SHOW ONLY DAY / NIGHT FIRES

To By default, the map shows both Day time and night time fires, to view only daytime day time fires, make may sure ADVANCED MODIS MODE is selected (as shown above). Click the "+" icon then click on "Night" so to deselect it and it is greyed out. To view only nighttime fires, click on "Night" to turn both back on and then click on "Day" so it is greyed out.

CONFIDENCE or TIME SINCE DETECTION

To view fires using Fire Radiative Power (FRP), Confidence or Time Since Detection, select "ADVANCED MODE" in the Layer List, then select the drop down arrow next to the word "Fires"  for the fire detections you want to change.
