On 19th Jan 1998 our Netware archive server CCN7 was switched off
and replaced by our new NT server SATPIX.NOTTINGHAM.AC.UK. The
name "CCN7..." now points to the SATPIX server but no commitment
is made to maintain the name indefinitely. For ftp users exper-
iencing difficulties with file paths on the new server please read
the section "ACCESSING THE ARCHIVE" below.

Our Archive server is now accessible over the web at:
http://satpix.nottingham.ac.uk
SERVICE OVERVIEW
The extremly popular Meteosat image service here at The University
of Nottingham has been set up to supply two main needs:
1) An ultra up-to-date source of the latest images available.
2) A rolling archive of recent imagery going back several weeks.
Both services are now offered via http and anonymous ftp.
We aim to receive and archive *EVERY* wefax image that Meteosat transmits
on either of its transponders. That's about 350 images per day of 42 different
scenes. The archive is deeper for some of these scenes than it is for others,
for example the D2 scene (Western Europe & North Africa in infra red) is currently
kept for some 90 days, while the testcards are only kept for 3 days.
ACCESSING THE "LATEST" IMAGERY
On the web:
http://www.nottingham.ac.uk/meteosat/
OR by ftp:
Host: ftp.nottingham.ac.uk
Dir: pub/sat-images
Files: *.JPG (see file naming conventions below)
ACCESSING THE ARCHIVE
On the web:
http://satpix.nottingham.ac.uk
OR by ftp:
Host: satpix.nottingham.ac.uk
Dir: /satpix/archive
Files: *.JPG (see file naming conventions below)
The archive starts at dir: /SATPIX/ARCHIVE
The next level of sub-directories is a list of scene names (see below).
The next level is a list of dates.
The next level contains the JPG files for that day and that scene.
The files are subscripted according to their Meteosat time-slot
FILE NAMING CONVENTIONS
Our file names are taken directly from the ID string tag which
every image carries with it as it is transmitted by Meteosat.
The tag specifies the scene name, time slot and date.
Image files in the "latest" service are named with just the
scene name. Files in the archive are named with the scene
and time slot and placed in a directory named according to the
date from the image tag, for example:
PUB/SATPIX/ARCHIVE/D2/07JUL96/D2_24.JPG
Where D2 is the scene name, _24 is the time slot (12 noon)
and 07JUL96 is the date.
METEOSAT SCENE NAMES
Name Description
==== ===============================
ADMN Eumetsat Admin messages
C02 Double resolution, NW quarter of C2D
C03 Double resolution, NE quarter of C2D
CnD n=1..9, VISible light image
CTH Processed cloud top height
CTOT Full Disc, VIS
Dn n=1..9, IR (infra red)
DTOT Full Disc, IR

ETOT Full Disc, WV
GMSN GMS Japan centred, IR
GMSS GMS Australia centred, IR
GOMS Russia centred, IR
LR USA relay South America, IR
LY USA relay North America, IR
LZ USA relay NE Aerica, VIS
TEST Test card
CnD, Dn & En images are of 1/9 th of the globe as seen
from Meteosat, n can take the value 1 to 9 as follows:
N
.---.---.---. Pretend that
| 1 | 2 | 3 | this square
|---+---+---| represents
W | 4 | 5 | 6 | E Meteosat's
|---+---+---| View of the
| 7 | 8 | 9 | Earth's globe
`---^---^---'
S
So D2, for example, would be an infra red view of the
Atlantic, Western Europe and NW Africa.
ARCHIVE STATUS
The file:
http://satpix.nottingham.ac.uk/satpix/latest/txt/report.txt
or
ftp://satpix.nottingham.ac.uk/satpix/latest/txt/report.txt
or
http://www.nottingham.ac.uk/pub/sat-images/txt/REPORT.TXT
or
ftp://ftp.nottingham.ac.uk/pub/sat-images/txt/REPORT.TXT
is our most recent archive status report and can be used to
determine the current depth to which each scene's archive is
maintained.
IMAGE ARRIVAL TIMES
Normally images appear in the archive and the "Latest" service
within a few seconds of them being received. Eumetsat publish
a "Meteosat Dissemination Schedule" which details which view is
transmitted at what time. See our web page for a copy of this or
http://www.nottingham.ac.uk/~cczsteve/metdis.txt
However, arrival times can easily be established by examining
the time stamps on the archived files.
** NOTE that where possible times are specified in GMT **
IMAGE STATE
The images we provide are unadulterated and as far as possible
exactly as Meteosat transmits them. The JPEG encoding has a
small impact on image quality but is for all intents and purposes
negligible. We also truncate the 2 lines of ID bits transmitted
at the start of each image.
NOTE that the caption, the country outlines and grid markers are
inserted by Eumetsat (NOT US) and so it's no good complaining
to me about this.
Also Meteosat DOES NOT TRANSMIT COLOUR IMAGES, any colour images
you may have seen are either not from Meteosat or have been
artificially produced by some colorisation algorithm.
Our home-made colour composite images, X2.JPG & XTOT.JPG are available
from the "Latest" service, and are created once a day at 13:00 GMT.
They are produced by painting the VIS, IR and WV scenes (of the same
view) in Red, Green and Blue and then combining all three into a composite.
The colours produced are meaningless and artificial but none-the-less
very pretty!
MOVIES
We provide 12 & 24 hour slide-show movie sequences of D2 images using
server-side push available to web users with a suitable browser (eg Netscape)
see the main web page. We also occasionally manually make the odd MPEG
sequence, once again these are available for download from our web page.
See also the excellent pages at Reading:
http://typhoon.rdg.ac.uk/Data/Global/europe.html#A01
Where they regularly take are our stills and animate them.

MIRROR SITES
------------
UK:
The British Atmospheric Data Centre (BADC) is the
NERC dedicated data archive and distribution agent.
Our Web address: http://www.badc.rl.ac.uk/
We mirror images of the Northern Atlantic, Europe
and North Africa in all channels, i.e. C2D (+ C02
and C03), D2 and E2, with the purpose of maintaining
a long-term archive of these images. Mirroring takes
place daily. The files can be easily downloaded from
our Web pages or transferred via anonymous FTP.
FRANCE:
OrageNet is a non commercial web site devoted to
"thunderstorm observation" in France.
It currently maintain a mirror site for some of your Meteosat
pictures: D2.jpg, C02.jpg and C03.jpg,
See the following URLs :
http://www.oragenet.org/meteosat.html
http://www.oragenet.org/meteosat-vis.html
http://www.oragenet.org/anim.html
Processings: "France area" is cut-off, contrast enhanced
and turned to "dark grey-blue" levels. A small movie
is build, the last 4 images are presented on the same
page, files are also archived. C02.jpg and C03.jpg are
combined before the "France area" is cut. In addition,
the clouds which are whiter than a given level are binarised
and put on our main map, where they appear as "grey dots" :
http://www.oragenet.org/carte2.html
The evolution during the last 30 min. is shown by
intersecting the last 2 binarised images, which gives
the direction and speed of the moving/growing clouds.
Some of the pictures are taken as a good example
of thunderstorm growing:

HUNGARY:
http://iris.elte.hu/meteosat
ftp://iris.elte.hu/pub/meteosat
Our site at the Dpt. of Applied and Environmental Geology of the Eotvos
Lorand University, Budapest mirrors the following images from the Nottingham
University Image Archive for the sake of enthusiastic amateur astronomers,
geologists and for everyone in Hungary interested in.
DTOT.JPG (renamed to MMDD-HH.w_ir.jpg)
D2.JPG (renamed to MMDD-HH.e_ir.jpg)
C2D.JPG (renamed to MMDD-HH.e_vis.jpg)
C03.JPG (renamed to MMDD-HH.ce_vis.jpg)
XTOT.JPG (renamed to MMDD-HH.w_col.jpg)
X2.JPG (renamed to MMDD-HH.e_col.jpg)
Downloading takes place six times a day at 7:00, 10:00, 13:00, 16:00,
19:00 and 21:00 MET /UT+1/ (MEDT /UT+2/ - from March to September).
Our ftp directory keeps the above images archive for 5 days and has the
symbolic links "curr_ir.jpg" and "curr_vis.jpg" pointing to the most
latest C03 & D2, respectively. These are also available in GIF format as
"curr_ir.gif" & "curr_vis.gif".
Our Meteosat HP offers the latest C03 and D2 for downloading both in JPG
and GIF formats, contains links to our FTP-directory and to the archive
site at ccn7.ccc.nottingham.ac.uk.
Animations are available via links to the Universidad Publica de Navarra
and the Instituto de Astrofisica de Canarias.

mirroring
ccn7.ccc.nottingham.ac.uk:satpix/archive/{d2,c03,c2d,ctot,dtot},
& /latest/{jpg,txt}
The archive/ files are kept for roughly 14 days
The latest/jpg directory is not mirrored completely.
Rather, the files d2.jpg, c03.jpg, c2d.jpg, ctot.jpg, and dtot.jpg
are maintained as symbolic links to the most recent images in the
archive/ mirror directory. That way, we avoid copying these files
twice, and having an out-of-date copy of the files due to the locking
problems on ccn7. I can offer to make available the scripts I use to
maintain the mirror archive.

ITALY
From: Paolo Ventafridda <venta@icom.icom.it>
Since May 1995 I am mirroring D2.JPG on http:/www.icom.it/meteo
This picture is downloaded automatically every 2 hours, converted
to targa raw format, reduced to cut off Africa, minimized to
400x250 and 200x125 jpg pics. I offer a slide show animation (also)
using server-push cgi to html 3.0 clients.
The aim is to reduce international trafic from Italy: italian users
are normally interested only in looking at the D2 pic.
I.com does not sell connectivity, we are not an IP provider.
We offer free services to people, and WWW housing to companies.

Date sent: Tue, 6 Feb 1996 15:17:56 +0100 (MET)
From: Carlos Amengual <amengual@sadeya.cesca.es>
The Sociedad Astronomica de Espana y America provides a mirror service
for the Meteosat images, getting the D2, E2, C2D, C02, and C03 JPEG
images. The D2, E2, C2D, C02 and C03 are renamed to eur_ir.jpg,
eur_irVA.jpg, eur_vis.jpg, euW_vis.jpg, and euE_vis.jpg respectively.
D2 and E2 are mirrored every three hours. The nine most recent D2 images
are kept in the archive, with the mentioned eur_ir.jpg name for the most
recent, eur_ir2.jpg for the previous one, and eur_ir9.jpg for the oldest.
The same scheme is used for the latest four images of the other types, the
visual ones being mirrored only during daytime.
You can reach the archive via WWW or FTP:
URL http://www.sadeya.cesca.es/meteosat.html
URL ftp://ftp.sadeya.cesca.es/pub/meteo/meteosat/
The service was intended to help spanish astronomers in planning short-term
observations.
