NBP0104 v2 readme  October, 2002

ADCP configuration:  

		- 8 meter depth bins (first bin 31)
		- 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Single Ping Data: Single ping data from this cruise have been archived, but are not yet 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 nbp0103 version 2 files contain data from the second attempt
at processing the NBP0103 data (processing by Jules Hummon at the University of Hawaii). A better reference layer calculation for this dataset was used in version 2 files.  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 (1 hr data files have been averaged).
No averaging has been done on depth.



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)=[];
