Colocalization between T-UGOm and observations

The command excalibur compute the colocalization between in-situ observations with a T-UGOm simulation and produce the difference.

IGN69=/ecola/share/tmp/training/geoid/ign69_wgs84-1-float.grd
SIMULATION=/ecola/share/tmp/training/gironde-2018/run-R15
DATA=/ecola/share/tmp/training/gironde-2018/insitu-obs

excalibur --meanlevel-offset 0.5 -s 30 \
          -p $SIMULATION \
          -c tugo.state-YYYY.MM.nc -g $IGN69 \
          $DATA/cnav181016_lam1_air_a2.track_fmt_300_lis \
          -o cnav181016-R15_B01_F00-2018-30sec.xyz

The output file is a table where each variable is on a different column:

#	Variable
0	time
1	longitude
2	latitude
3	tide + storm surges model correction
4	GPS sea surface height/WGS84 ellipsoid
5	IGN69/WGS84 ellipsoid
6	GPS sea surface height/MSL (IGN69+50cm)
7	GPS sea surface height – model correction
8	GPS (boat) speed
9	flow speed
10	boat relative speed (8 – 9)

To plot the pixel cloud with POCViP use the command bellow and refer to this example:

pocvip -f cnav181016-R15_B01_F00-2018-30sec.xyz
