The low-rate picture transmission (LRPT) is a digital transmission system, intended to deliver images and data from an orbital weather satellite directly to end users via a VHF radio signal. It is used aboard polar-orbiting, near-Earth weather satellite programs such as MetOp and NPOESS .
The first weather satellite to be considered a success was TIROS-1, launched by NASA on April 1, 1960. [5] TIROS operated for 78 days and proved to be much more successful than Vanguard 2. Other early weather satellite programs include the 1962 Defense Satellite Applications Program (DSAP) [ 6 ] and the 1964 Soviet Meteor series .
The NASA website hosts a large number of images from the Soviet/Russian space agency, and other non-American space agencies. These are not necessarily in the public domain. Materials based on Hubble Space Telescope data may be copyrighted if they are not explicitly produced by the STScI . [1]
Since 20 March 2018, Meteosat-10 provides an operational European 'rapid scan' mode service (the MSG RSS service first commenced in May 2008), with images of Europe every 5 minutes. Since 20 February 2018, Meteosat-11 provides the main full Earth imagery service over Europe and Africa (with images every 15-minutes).
The movement of air in the Walker circulation affects the loops on either side. Under normal circumstances, the weather behaves as expected. But every few years, the winters become unusually warm or unusually cold, or the frequency of hurricanes increases or decreases, and the pattern sets in for an indeterminate period.
The ocean is absorbing approximately 90 per cent of the heat trapped by greenhouse gases
The ABI takes images with three different geographic extents, [26] with each image produced as a combination of stitched west-to-east narrow image scans made by the instrument. [30] In the default "flex" mode (scan mode 3) of operation, the ABI produces full-disk images of the Earth every 15 minutes, with a spatial resolution of 0.5–2 km (0. ...
