Suggestion: ability to change units in INFRA+
...I am sorry, but what actually I can estimate with INFRA+ map? How to correctly "read" this map? Is it ascending flows because hot? So CAPE?
INFRA and INFRA+ is not a forecast map.
It is an image taken by satellites orbitting at 36.000 km above Earth.
Infrared radiation emitted by the earth's surface, or by other objects like clouds,
gets transmitted to the satellite with very little absorption along the way.
Warmer objects emit more radiation than colder objects.
Computers convert the amount of infrared radiation received by the satellite to a temperature (formally called a "brightness temperature").
Finally, these temperatures are converted to a shade of gray or white
to create an infrared satellite image.
Conventionally, lower temperatures are represented by brighter shades of gray and white
while higher temperatures are represented by darker shades of gray.
Some infrared images are in grayscale (INFRA),
while others include all the colors of the rainbow (INFRA+).
The color scheme highlights very low temperatures.
In INFRA+ , blue stands for -33C (240 K) and red for -73C (200 K).
Well, as temperature typically decreases with increasing height in the troposphere,
and if we make that assumption, then we can equate cloud-top temperatures to cloud-top heights.
Windy provides another tool named "sounding".
Let's use it.
Right click on location (A) then "sounding".
As you can see, the cloud top temperature (-33 C)
equates to 29,108 ft (8872 m) cloud top height.
