NBP0202 v2 readme  Feb 5, 2003

ADCP configuration:  

		- 8 meter depth bins (first bin 31)
		- 8 meter pulse length
		- 5 minute ensembles

Full ADCP onfiguration files are located in the cruise pages on our website:

Single Ping Data: Single ping data from this cruise have been archived, but are not yet 
available for distribution by ESR.

		
	
Quality:  The nbp0202 version 1 files contain data from the first attempt
at processing the NBP0202 data (processing by Jules Hummon at the University of Hawaii).   Additional editing may also need to be performed.  So, use caution when working with this data.  Questions regarding this data set should be addressed to Susan Howard at howard@esr.org.


Format:  The matfile contains the following variables:

u    		- east-west velocity
v    		- north-south velocity
bin_depth 	- depth of each u and v data point
dec_day		- time in decimal days ( Noon on Jan 1, 2001 is 0.5 )
year_base 	- year of cruise 
start_day 	- date and time of first data point
end_day 	- date and time of last data point
lon  		- longitude


Files exist on a 5 minute or 1 hour time base. The 5-minute file is the processed 
ensemble-averaged output from the ADCP. The 1-h file is a time-average of good data from 
the 5 min ensembles in each 1-h time interval. Times given are the times at the center of 
the averaged time interval.  

No averaging has been done on depth. Values are listed for the originally recorded depth 
bins. Vertical averaging is inherent in the choice of pulse length. 



Note:  Bad or missing data is listed as NaN

To remove sections of NANs when lat and lon are NaNs, insert following lines of 
code into your matlab script:

badi=find(isnan(lon));
lon(badi)=[];
lat(badi)=[];
dec_day(badi)=[];
u(:,badi)=[];
v(:,badi)=[];
