PGH/TSI/M1 - Reprocess: Truncated start of daily movie

The TSI names the daily tsimovie file with the UTC date in which the sun rises and the 
file begins. At PGH in the summer, the sun rises just before 00:00 (earliest sunrise is at 
23:41) so the daily movie should start and the file be named with the date that is prior 
to much of the remainder of the file. 

The TSI at PGH was set to start automatically each morning at 23:58 UTC but it should have 
been set to start about 20 minutes earlier. Therefore, sky images for the first few 
minutes of each day through 7/19, when the sun began rising after 23:58, were not collected. 

On 8/26, the times of the scheduled tasks were adjusted to those that should have been 
used from the beginning of deployment.

Since only a maximum of three images were collected prior to 00:00 UTC each day, it will 
be less confusing for data users if these images were removed from the daily movie files 
through 7/19. 

Reprocessing has been requested.  In the meantime, the pghtsimovieM1.a1 files have been 
renamed to reflect the date the bulk of the data represents.

PGH/TSI/M1 - Ingest Problem

A minor error was made with diagnostic metadata attribute sunny_thresh when the TSI ingest 
was updated.

PGH/SONDE/M1 - Wind data missing

The BBSS GPS antenna head was struck by lightning causing it to fail.  Wind speed and 
direction data are missing for the time period listed.

PGH/SKYRAD/M1 - Reprocess: Incorrect calibrations

During the entire India deployment the Skyrad system was configured with incorrect 
calibration coefficients for the shortwave instruments. The program hadn't been updated since 
the previous deployment in the Azores.

The instrument mentor, site personal and OSS support have attempted to best determine the 
serial numbers of instruments installed at PGH during the deployment period.  The 
following instrument data will need to be reprocessed with the following correction multipliers:

PIR1-DIR(down_long_hemisp1): OK, no correction required
PIR2-DIR(down_long_hemisp2): OK, no correction required
Diffuse 8-48 (down_short_diffuse): 116.95(correct)/120.91(incorrect) = .96725
NIP (short_direct_normal): 127.03(correct)/124.97(incorrect) = 1.01648
PSP-DS (down_short_hemsip): 111.29(correct)/108.48(incorrect) = 1.02590
IRT: calibration should be validated by instrument mentor (Vic Morris): mult=26, 
offset=173.2

Correct serial numbers:   
Diffuse 8-48 (down_short_diffuse): 34066
NIP (short_direct_normal): 34135E6
PSP-DS (down_short_hemsip): 33942F3
