The other image is not shown.Ĭontrast enhancement is performed only on the NOAA channel B image as per the Contrast setting in the Options menu. Black and white Creates a black and white image, setting darker pixels to black and lighter pixels to white.Ĭontrast enhancement is performed only on the NOAA channel A image as per the Contrast setting in the Options menu. Disables gamma, sharpening, rotation, despeckling, and other enhancements.Ĭontrast enhancement is performed as per the Contrast setting in the Options menu. No attempt is made to temperature normalise IR images. Typically used to output images for further processing by other software Pristine images are unenhanced, but unlike raw images have been normalised to produce images which represent, as best as the software is able to, the original digital data. Produce pristine output (best representation of original digital data). Produce a normal image, using Gamma, Sharpening, Despeckling, etc settings. Note, that some of the images processed with special methods, which allows to see the 3-D picture of ground and clouds, so if you want to see correct image you have to use special glasses, description of image contains description of glasses too. Description of image contains method of decode RAW-picture. So I propose you select image most informative from synoptic-professional point of view, which I will place to site in addition or instead of images which I placed before.īelow I place images which I got as RAW-file and then process by different methods. May be my method was wrong, may be I lost important information, choosing just attractive picture. What method is the best? To me - I just choose the most attractive picture and placed it to site. The Weather Satellite Receiver is now being tested ready for this year's Jamboree on the Air.WXtoImg program allows decode the satellite image by different methods. Further information is available from NOAA and from the WXtoIMG websites.
A band of interference can be seen occuring on several of the images - cause as yet unknown! The software in use is WXtoIMG - responsible for recording the wav files to disc, then decoding the information and applying various palettes to the data to achieve the images seen here. In addition to this, other lower passes can sometimes yield good results from this location.
The satellites orbit the earth every 90 minutes, however with the rotation of the earth this means we typically get 2 good passes from each satellite every day. There are four NOAA satellites in service - 15, 17, 18 and the newest NOAA 19 (still undergoing trials). These are received on 137 Mhz currently on a colinear antenna connected to a Dartcom sythesized VHF satellite receiver. These are the latest weather satellite images received from the low earth orbiting NOAA satellites.
