EUMETCastView v2.0.8

EUMETCastView v2.0.8 Release Notes

EUMETCastView v2.0.8 now uses the Qt 6.9 API.

This release includes numerous bug fixes and improvements. NOAA-21 is now supported, whilst NOAA-19 has been completely removed from the program.

The most significant change concerns video creation. Meteosat-12 is now supported. Instead of using threads to generate video images, a new process is now started for each image that needs to be created. This approach has the advantage of isolating each process, eliminating problems when reading netCDF files.

You can specify in the video widget how many processes will run concurrently. I recommend using one process per CPU core on your computer.

Since each video frame is a general vertical perspective image, the program only reads the segments (for Meteosat-12) that are necessary to create the projection image.

EUMETCastView v2.0.7

For Meteosat-10 / -9 and MTG-I1 it's possible to add a fourth spectrum channel "N" (besides R, G and B ) that will be displayed in the night side of the earth. For Meteosat satellites you can set this fourth spectrum channel for all the infrared bands("IR_039" and lower). For MTG-I1 this means from band "ir_38" and lower. If you want white clouds for the night side, than you have to set the inverse image.

EUMETCastView v2.0.6

In the list of segments for the Himawari-9 satellite a new column is visible when the center of the moon and the center of the earth are within 9°. The integer number shows the percentage of illumination of the moon at that moment. This means that there is a chance that the moon is visible in that time frame in the image. (see the program WhereIsTheMoon). The Advanced Himawari Imager constructs the image from north to south. This means that the calculated moon positions in the north are closer to the time of the image. Moon positions in the south are closer to the next 10 minutes frame.
There is also a moon overlay in the image that indicates the different positions of the moon. An exact calculated position of the moon in the image is not possible due to the fact that the scanning of the earth of the AHI imager is sometimes interrupted for other tasks of the satellite.

EUMETCastView v2.0.5

When segments are missing the image is still created.

EUMETCastView v2.0.4

Solved small bug in list MTG-I1 segments.
CLAHE button for AVHRR images.
"Update Image" button for AVHRR images.

EUMETCastView v2.0.3

The MTG-I1 image projections for the channels ir-38 to ir_133 are now like it should be.
Also for the 3D Globe projections.

EUMETCastView v2.0.2

In this edition of EUMETCastView, the file names of the MTG-1 eumetcast broadcasts have been adjusted to the new situation.

The CLAHE procedure has also been improved. A conversion is now first made from the RGB color space to the Lab* color space and only then a CLAHE procedure is carried out on the 'lightness' channel. This improves much the colors of the picture.

Included in the zip file is a small program called EumetcastDirUpdate. It allows , depending on the ini file, that the received Eumetcast files are moved to a YYYY/MM/DD directory.

EUMETCastView v2.0.1

Some bug fixes and this release is compiled with the latest MSYS2 libraries.

EUMETCastView 2.0.0

This release supports the FCI images from MTG-I1.
I also changed the display system in EUMETCastView to a more performant display system in Qt, called QGraphicsView. This was necessary because the old display system was rather slow for the big images produced by MTG-I1.
A number of bugs in the histogram matching are also solved .
With the introduction of the new image system , new bugs will undoubtedly appear...

EUMETCastView 1.5.7

Update switch Meteosat-10/Meteosat-11
