Get data for wildfires observed by the NASA MODIS satellites

Contributed by: Arnoud Buzing

ResourceFunction["UnitedStatesWildfireData"][]

gives a structured Dataset for wildfires observed by the NASA MODIS instruments on the Terra and Aqua satellites.

Details

MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (originally known as EOS AM-1) and Aqua (originally known as EOS PM-1) satellites.
Terra’s orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon.
Terra MODIS and Aqua MODIS are viewing the entire surface of the Earth every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications).

Examples

Basic Examples (2) 

Get the current wildfire data:

In[1]:=
ds = ResourceFunction["UnitedStatesWildfireData"][]
Out[1]=

Process the salient data columns:

In[2]:=
geo = Normal[ ds[All, {Red, AbsolutePointSize[2], Point[#Location]} &]];

Plot the wildfires:

In[3]:=
GeoGraphics[geo, GeoRange -> EntityClass["AdministrativeDivision", "ContinentalUSStates"], GeoBackground -> "Satellite"]
Out[3]=

Focus on California wildfires:

In[4]:=
GeoGraphics[geo, GeoRange -> Entity["AdministrativeDivision", {"California", "UnitedStates"}], GeoBackground -> "Satellite"]
Out[4]=

Focus on wildfires near San Francisco:

In[5]:=
GeoGraphics[geo, GeoRange -> GeoDisk[Entity[ "City", {"SanFrancisco", "California", "UnitedStates"}], Quantity[200, "Miles"]], GeoBackground -> "Satellite"]
Out[5]=

Plot the brightness of each data point on a histogram:

In[6]:=
ResourceFunction[ "UnitedStatesWildfireData"][][Histogram, "Brightness"]
Out[6]=
