MISS profiler pc seems to be having network connection problems.
The consensus files haven't been making it across to the data manager
since last evening, however the profiler is otherwise running okay.

The raw spectral files are being recorded okay so consensus data can
be recovered post-project.

Opening explorer showed that the k drive looks okay and is open,
and there was no error message in POP.  Rebooting computer didn't
help. Did rass run at 1635 as test but still not transfering data.
Since there's an EOP on now and the raw data is being recorded, 
I won't any further tests just now.

Doing backup to an external UBS disk.

Tried connecting using firewire (daisy chained to Maddog DVD drive)
but it wasn't recognised.  So disconnected printer from USB port
and plugged in disk there and a Konqueror window popped up.

Backing up (from /data_source directory) using command:
rsync -v -u -r -t * /media/usbdisk/data/miss/data_source/

Moved MISS back to it's base site near Manzanar.

Lat 36.726 Lon -118.134 Alt 1168m.

Trailer close to hill, orientated at 315 degrees.
Met tower 20m to NW.

Profiler set to 60 metre mode for tonight and tomorrow nights EOPs.

Help from the students (Serena, Heather, Alex).
Filmed by videographer and Vanda.
Smooth move, although conditions a little breezy.

Some problems with rack campbell so some solar radiation measurements,
cycling power on it seemed to fix it.

Generator was serviced today. RASS was turned off from 17:10 unti 18:38 utc
w2hile sywstem maintinaqnce wasw performed.

Switched profiler to 100 meter mode at 22:10 UT for tomorrows IOP.

Also trailer waas slightly tilted.  
Putting electronic level along front side of profiler, 
was tilted 1.3 deg too high on east side and 0.4 deg along right side.
(0.1 along left side and 0.7 along back so overall tilt prob about 1 deg).
Lowered front right leg a little and now level to within 0.2 degree.

RASS was off overnight while Lou did repairs to supports on dish,
but on from 1830.

Keeping winds mode at 60m for tonight's EOP.

MISS now setup back at Manzanar base site.

Trailer bearing 316 degrees true north.

RASS is not being set up to give Lou a chance to repair the speaker
dishes.

The radiation plots stop at 20060416,00:30 UTC for an unknown reason.  There
are no data between then and 20060416,07:00, but for some reason those data
do not appear in plots.  With this startup the ingest and plotting appear
to be working again.  I have no explanation for the dropped data.

The radar has been put in 60m mode for the impending EOP.

21;25 UT shutting down for move to OV2.

Trailer bearing 30 degrees from true north.

Some bad clutter in the SE beam.  "Not great in the NW either," says Bill.
"The other two beams aren't so bad.  Little bit of RFI."

RASS temperature range changed to -10 to 30 degrees C.

The laptop hung after the first startup.  That's the second time I've
seen that.  The power button seems to be having problems.  It has to be held
down or pushed different directions sometimes to trigger it.

We tried calibrating the KVH with wide, slow, 2-minute circles at the
Manzanar airport, according to the tech support email, but the KVH readings
are still just plain wrong.  KVH ingest remains turned off.

Mike transferred some fuel from truck tank to rental generator tank.  He
says we need to add some fuel to the large fuel tank based here at the site.

Everything else operating normally.

Oh yeah, it's very windy.  The inside of the equipment cabin is covered with
dust.

NIMA results have not been sent for 3/28 and 3/29, so I came to check on it.

I noticed the gps ingestor (gps_adam) was taking up lots of cpu, 80-90%.
strace showed it looping through select and read: select() was returning that the serial port was ready, but a subsequent read returned 0 bytes:

select(6, [3 5], NULL, NULL, {300, 0})  = 1 (in [5], left {300, 0})
read(5, "", 512)                        = 0
select(6, [3 5], NULL, NULL, {300, 0})  = 1 (in [5], left {300, 0})
read(5, "", 512)                        = 0
...

Restarting the gps appears to have fixed it.  Perhaps this a bug in the edgeport or serial driver.

I then noticed 3 wppp processes running at the same time for the same day, so something got hung up or slowed them down.  I killed all of those and restarted the processing for 3/29.  According to the log for 3/28, a profiler parameter change is preventing that whole day from being processed.

It took about an hour to process one whole day, so I increased NIMA run times to every four hours.

There were old data files from 2/18 with zero length which were causing error log messages in zebra, so I removed them.

Hal and I put on the new anemometer today and renorthed it. 

Visiting site today, getting ready for EOP2.

Need to fix MISS met tower tomorrow.

Profiler starting to pick up a little interference again this morning.

Source of RFI is unknown.

We moved the Met tower about 30 m to the NE at 2345 UTC so that it would be
out of the line of site of the MotoSat.

Profiler seems to be picking up some interference since about 20 UTC,
this interference has swamped the signal between 22 and 00 UTC.

Source of RFI is unknown.

We went through a number of steps to get sat com back on line.

1) stowing dish and cycling power

2) check all connections in trailer and on roof, some of the
connections had gotten a bit loose.

3) moved tower - it had been in line of site of antenna so the 
thinking was it was interfering with reception.


4) after moving tower, restowing dish and powering back up,
the satcom came back on line

Shut down MISS for move to north of Independence for IOP 2
18 UT March 5

The wind at the surface is out of the west and the dishes were in the south. There was little rass signal in the profiler, so I moved the dishes to the sides and it appears to have helped.
