GLOBEC - timedateparams job
20070315

The task is to add a time column like yrday_local, yrday_gmt, gmt_date and gmt_time 
(and eventually time_epoch) to all the data objects in globec (also soglo, NEC, NEPac)
 in order for the data to be plotted over time periods.  

We'll start with SOGLOBEC, alongtrack.  There are 11 cruises.  
These are all in gmt so we'll add gmt_date and gmt_time to the front of the list.  
If the PI porvided yrday_local, we'd use that.

This data is located in /data12/sodata.  Each cruise has its own subdirectory.
  *.ind contains:  (see defgb manual for list) 
datafile name, removals, transvar, dispwidths, datafieldopts

alongtrack.ind

/data12/sodata/lmg0103/JGOF/JGOF/ this is where 

Compare variables in original dat file, ind file (transvar list).  
The transvar list result is what appears online.  
Keep all the unique variables whether or not they're used.  
For alongtrack, we added a variable to varlist  for yrday_gmt, day_gmt, month_gmt

---------------------------
lmg0106alongtrack.ind file:
datafile = /data12/sodata/lmg0106/rvdas/JGOF/lmg0106.alongtrack
datafieldopts = \ separators = '\t \n'
removals = \ gmtdate; dummy1; gmttime; day_gmt; month_gmt;
     gmttime; day_gmt; month_gmt can added after you test
timedateparams = /data12/sodata/lmg0103/JGOF/JGOF/lmg0103.timedateparams
transvar = \ date = date_gmt; mPAR = par_d; sstemp = temp_ss; sscond = cond_ss; sssal = sal_ss; wspd_t = wind_speed_c; wdir_t = wind_dir_c;	airtemp = temp_air; rel_hum = humidity; metpress = press_bar; PSP = radiation_l; PIR = radiation_s
--------------------------

lmg01003.timedateparams:

invar1name = gmtdate  
invar1template = dd*mm*yy

invar2name = gmttime
invar2template = HH:MM:SS

#invar3name = ampm
#invar3template = p

#outyearname = year

outdayname = day_gmt 
outmonthname = month_gmt
outtimename = time_gmt

outjulianname = yrday_gmt
outjulianformat = v
------------------------

put all variables in the top-level .dat file (eg. lmg0103.alongtrack)
	yrday_gmt	month_gmt	day_gmt	time_gmt

example:
#
# R. Limeburner, Ch. Scientist

...
------------------------

Step by step:
* open a previously edited (good) .ind file	eg. lmg0103alongtrack.ind
* open a not yet fixed .ind file
* make current .ind match good one:
	1. change datafile = name and path
	2. edit removals
	3. don't include....??
	4. add timedateparams = /data12/sodata/lmg0103/JGOF/JGOF/lmg0103.timedateparams

* open *.alongtrack and put new varnames at end.  Save file.
		yrday_gmt	month_gmt	day_gmt	time_gmt
* test in a second xterm window so you can change the ind file name.
	go to the current directory: eg. cd /data12/sodata/lmg0103/JGOF/JGOF/
	/data5/globec/methods/defgb "@lmg0103alongtrack.ind"
	use !! to repeat last command (or arrow-up in bash)
* test in web window.  Look for presence of new time columns, lined up columns, no errors.
