This page compares the 0.64um, 0.80um/0.86um, and 1.61um bands from
the Advanced Baseline Imager and the Meteostat Second Generation satellites.
Also included in this page are the seven ABI Bands in visible and nearIR spectrum.
Throughout the following subpages there is often a reference to difference images of
two channels or bands. For these differences to have meaning there must be
a reference point for comparison. Below is a spectral plot of a clear and cloudy
scene over the SCAR-B scene. Notice radiance values going between a clear sky and
a cloudy sky can differ as much as eight watts. Refer to this image when attempting
to deduce the signficance of the following difference images.
The above image plots both the ABI (blue) and MSG (green) 0.64um and 0.80um/0.86um bands. Also plotted in red is the radiance of a clear sky over
the SCAR-B scene. Notice the 0.80um/0.86um are quite different. MSG is centered on 0.80um and ABI is centered on 0.86um. Click here for a more
detailed page about the differences of the ABI and MSG 'vegetation' channel.
The above image plots the ABI (blue) and MSG (green) 1.61um band. The radiance plot is taken from the same clear SCAR-B scene as the first image. Click here for a more detailed page about the differences of the ABI and MSG 1.61um channel.
Above is the visible and near IR proposed ABI bands. Again the radiance plot is the same clear SCAR-B scene as the previous two images.
