An image satellite weather folks check.To use the pictures from the image satellite weather specialists need to process and customize the information. How do we interpret satellite imagery?
For example, see a sample satellite image for Calgary, Alberta Canada. We can derive planet temperatures, humidity pictures, cloud pics and wind data from the satellite depictions. Both for identifying long-term trends and providing the greater precision needed for short-term weather predictions, sometimes called nowcasting. It has other uses. Satellite pix offer us enhanced perspective for use in
air pollution
studies for instance. Weather satellite historyThe first weather satellite: The world saw Tiros-1 (1 tiros) launched in 1960, USA.Since then we have become used to a That was brief. Are you in the satellite business? Selling satellite receivers and signals? Or do you have anything to do with imagery? If so, sell your stuff online. Can I make it easier?

Geostationary?A satellite can be engineered to fly with a perfect combination of acceleration, speed, velocity and height so that its position above a particular spot on the rotating earth never changes. That's what geostationary means.
It has to be over the equator for this to work. And since it is so high, around 22,000 miles or 36,000 km, it can give us a good equator map and cloud pictures over most of the earth, except for the poles. It has to go nearly 7,000 miles or 11,000 km per hour relative to the earth's axis to stay properly positioned. Portable weather stations, kind of…We receive a fresh image satellite weather snapshot of varying energy-frequency-wavelength values for a large area of the planet every 15 minutes. These are quite good for animating satellite photos.Five satellites allow us to see the entire earth between around 60°N and 60°S. They linger above the equator at 75°W, 135°W, 140°E, 70°E and about 0°, the prime meridian. What's even better, if one of the satellites fails, the others can reposition themselves to compensate for the shortfall until it gets working again. Onboard transmitters then send the data to the ground where computers overlay the

maps. The completed image then goes back to the satellite for worldwide distribution to forecast centres,
tv stations
and whatnot.

Polar orbiting satellites, which fly at much lower elevations, can see much closer and clearer, but not very far and so they have to move across the earth to get a broad image satellite weather picture.Only 500 miles/800 km up or so, thee polar orbiting satellites This is fast enough so that each satellite's orbit remains fixed relative to the sun and it always makes its northbound journey near noon. As a result each place gets its photo taken at roughly the same time every day. The industry calls this time-coordinated quality sun-synchronous. Visualize the satellite photos resembling ribbons stretching up and down around the earth. Naturally, there will be increasing overlap closer to the poles. The extra data in these regions are used for making more complete North Pole maps. This increased temporal resolution, frequency, gives high-latitude meteorologists good North Pole pictures and usable animations. That's very important to these people because of the poorer image satellite weather photo quality from the geo-stationary satellites in these Polar Regions.
The big picture comparisonThese two types of satellites provide us with at variety of angles for interpreting the imagary and making sense of the chaos.Geostationary - Steady, high frequency image satellite weather pictures and large area photographs. Good for animated satellite displays. Polar Orbiting - Greater image satellite weather resolution for studying and analyzing photos, but not for animating them. This one's also less costly.
