253: RADAR, Site ISS4 (Los Mochis), Wed 04-Aug-2004 18:01:00 GMT, Data Backup
Profiler was shutdown between 16:40 and 18:00z so data cold be backed up.
name_LMM03 and name_LMM04 cds were made.
115: RADAR, Site ISS4 (Los Mochis), Sat 17-Jul-2004 13:50:01 GMT, Profiler data backup and down time
More Profiler backup today, to clear the disk as much as possible.

Backed up the PROFILER SPC files.
Day 04194-04198 (July 12-16)
Also backup up \data\test files directory and deleted them

Profiler down from 1405 through 1435 for this process.
(and use of CD writer to copy PC-208W etc.)
Can read (dir) disk on GLASS-pc; ok.
Also note SPC files are present on ISS4 workstation
Deleted backup up files

Made two CD copies. Will take one with us. Other stays at ISS4
Volume name is directory: NAME_LMM02.

Now free disk space 1.80 MB. Disk use each day is about 73 MB.
Disk write at 8.0%



111: RADAR, Site ISS4 (Los Mochis), Sat 17-Jul-2004 02:36:47 GMT, Profiler data backup and down time
Backed up the PROFILER SPC files today.
Day 04179-04193 (June 27-July 11)
Profiler down from 2035 through 22:25 for this process.
Checked a few days on laptop; ok.
Made two CD copies. Will take one with us. Other stays at ISS4
Deleted files.
Volume name is directory: NAME_LMM01.

Now free disk space 1.32 MB. Disk use each day is about 73 MB.

1. PROFILER ERRORS
------------------
At 20Z today (15-July) we began getting the "sampling not finished within
5 seconds" message (bottom of profiler screen). This happened intermittantly
over the next few minutes. When I paused POP the PC response was bumpy.
Sometimes fine, but with pauses. At the same time we were performing a full
system backup on the ISS-4 workstation. This backup progress also seemed
bumpy. I waited until the backup was done and rebooted the POP PC. No errors
since.

No chance to backup the profiler PC. Manana?


13: RADAR, Site ISS4 (Los Mochis), Tue 29-Jun-2004 04:12:51 GMT, RASS NHTS limit?
RASS NHTS

Found a strange problem with RASS.
If NHTS is greater than 23 then strange spectra than appeared a little like RFI.
Spectra at all heights were almost identical with some strong feature that didn't change from dwell to dwell.

See RASS spectra around 4 UT on June 29 for examples.

Found that the spectra appear okay as long as NHT is less or equal to 22.

ICRA Averaging.  Spectra are being saved.

Consensus files are written via trailer network to data manager computer.

POP moments are transmitted via serial cable to data manager to generate SOAP plots.

Once per day (after 0Z) spectra are copied for data manager for archiving and NIMA processing.

Signals are fairly clean apart from a little moving clutter around 800m.
There is an airport radar about that distance away to the east.
The antenna was orientated to put a null in that direction.









9: RADAR, Site ISS4 (Los Mochis), Tue 29-Jun-2004 02:19:49 GMT, Profiler labelling and wind directions
PROFILER LABELLING AND WIND DIRECTION

Profiler labels under the antenna did not match the labels externally on 
the antenna frame.  The effect was that the beam directions were 90 degrees out,
so we had to add 90 degrees to get the correct wind directions.

Compared winds with Topolobampo pibal sounding and now seem to agree.

As of 1:45 UT on June 29, the directions are correct.
