Using OpenADDE servers with HYDRA
to read GOES and MSG data
In order to use local (McIDAS) AREA files for GOES and MSG
with HYDRA, it is necessary to install the OpenADDE servers on your
machine and configure them appropriately. This page contains some
notes about this.
Install OpenADDE Servers
Special note for Windows XP.
Note: if you are installing on Windows, you must first obtain
Windows Services for Unix (SFU) from
<http://www.microsoft.com/windows/sfu/>. Note that you must
install this package as an Administrator, and during the install, you must elect to install the GNU gcc compilers and associated files. Please
note:
- You will save yourself a lot of grief if you do the
OpenADDE and SFU installs by first granting "administrator rights"
temporarily to the user account that normally uses the
computer.
- Make sure you create a HOME
directory from the top level: "/home/user" -- this can be done as
a symbolic link after installing SFU.
- Do not use a directory name with embedded space characters!
Comments for all operating systems.
Please go to the page at:
<http://www.ssec.wisc.edu/mcidas/software/openadde/>
to obtain
the OpenADDE servers. Follow the instructions on this page to do
the install. Please note: the install files should be put
into the $HOME directory of the user you choose and the installation
run from there. This will create a an "openadde" directory for
all the installed files; you may remove the installer files and scripts
afterwards.
Configure the ADDE servers
After you install the OpenADDE servers, you must also configure
the ADDE server's catalog file, RESOLV.SRV for use with
HYDRA. This file will be found in the $HOME/openadde/data
directory for the user underwhich you installed. Configure
the RESOLV.SRV file to read like this:
# Example McIDAS RESOLV.SRV file
#
# Fields:
#
# N1= Group name
# N2= Descriptor name
# TYPE= Data type (Only IMAGE supported by free servers)
# RT= Realtime (Y/N)
# K= File format
# R1= Begin file number
# R2= End file number
# MASK= Filename mask for data files
# C= Comment
#
# Examples:
#
N1=EAST,N2=FD,TYPE=IMAGE,RT=N,K=AREA,R1=1,R2=99,MASK=AREA00*,C=GOES-EAST full disk,
N1=WEST,N2=FD,TYPE=IMAGE,RT=N,K=AREA,R1=100,R2=199,MASK=AREA01*,C=GOES-WEST full disk,
N1=MSG,N2=FD,TYPE=IMAGE,RT=N,K=AREA,R1=4000,R2=4999,MASK=AREA4*,C=MET-8(MSG) 3-km HRIT FULL DISK IMAGER DATA CHANNELS 1-11,
These three entries specify that:
- GOES East AREA files will be named AREA0001 through AREA0099
- GOES West AREA files will be named AREA0100 through AREA0199
- MSG AREA files will be named AREA4000 through AREA4999
Note that all these AREA files should be full disk, maximum resolution!
Finally, the actual AREA files must reside in this directory or you can
alter the MCPATH variable (in the $HOME/.mcenv file) to search more
directories.
