Satellite Variables

Satellite Variables
The satellite datatype allows you to access our worldwide satellite sector which is composite from 5 domestic and international satellite imagery. 


Infrared

API Query: datatype=satellite&var=IR

Weather Central combines the data from five international satellites to produce a worldwide satellite composite.  The data comes from two United States run satellites, two European run satellites and one Japanese satellite.  The satellites use infrared scans that measure the temperatures of the surface that it is scanning.  Since clouds are located high up in the atmosphere they return much cooler temperatures than the surface.  This allows meteorologists to show which areas are cloudy and which are sunny.  This product is 4km resolution and updates every 6 hours.  This datatype is only available for tile requests

Infrared Plus

API Query: datatype=satellite&var=IRPlus

The Infrared Plus product is a worldwide composite, just like the Infrared product (above).  The main difference is that the Infrared Plus product updates every 30 minutes (with the exception of the European satellites which only update every 6 hours).  This datatype is only available for tile requests
