Comment on Tropical Storm Bertha by scott.bachmeier

Neither the ozone layer nor global warming have anything to do with this particular cyclone interaction. We occasionally see similar “Fujiwhara” type interactions between cyclones over the open oceans, and the influence of long-term climate change or lower stratospheric dynamics would be negligible.

This is interesting information. Cool satellite
pictures showing what's going on with the cyclones. Does the data here reflect any changes by the ozone layer, or global warming that may have contributed to these outcomes?

Comment on Fire activity in Canada by scott.bachmeier

There are two types of InfraRed (IR) satellite imagery shown here: GOES (which orbits at an altitude of about 35,800 km above the Earth), and MODIS (which flys much closer to Earth at an altitude of about 705 km). The spatial resolution of the GOES IR imagery is about 4 km, but the MODIS IR imagery has a significantly better spatial resolution of 1 km. If you try to “zoom in” for a closer look, the satellite image pixels will get larger, but you will not gain any additional information.

With the color enhancement applied to these GOES and MODIS IR images, hotter pixel temperatures are seen as you go from black to red to yellow colors.

ohh..so hot temperatures appear in black on the satellite images?
one more question sorry to bother you, the camera that shoots these images it is infra red as I understand, how far is it above earth? and how much can you zoom and still have a vivid picture?
are there other types of cameras used in these kind of activities?

Thanks for your help

The active fire “hot spots” appear as the darker black pixels on the GOES-11 3.9 µm shortwave IR images, or yellow to red pixels on the MODIS 3.7 µm shortwave IR images. In addition, the brighter white pixels on the 2.1 µm near-IR “Snow/Ice” channel and the darker red pixels on the Land Surface Temperature also denote the locations of the hottest active fires.

I am quite new to this and trying to learn, where exatly do I see the fire?

Thanks

This is a very interesting case. I will share this with some of my colleagues at Dalhousie University.
