Greetings,
I would like to retrieve csv files of MSL, wind direction, and wind
speed for specific points, that is, a sounding of forecasted wind data.
I am trying to subset the grid accessed through:
http://motherlode.ucar.edu:8080/thredds/ncss/grid/fmrc/NCEP/NAM/Alaska_11km/NCEP-NAM-Alaska_11km_best.ncd/pointDataset.html
and my query url looks like this:
http://motherlode.ucar.edu:8080/thredds/ncss/grid/fmrc/NCEP/NAM/Alaska_11km/NCEP-NAM-Alaska_11km_best.ncd?var=Wind_direction_from_which_blowing&var=Wind_speed&latitude=55&longitude=-160&time_start=2007-08-13T06%3A00%3A00Z&time_end=2007-08-24T00%3A00%3A00Z&temporal=point&time=2007-08-13T06%3A00%3A00Z&vertCoord=&accept=csv&point=true
That is, I am testing with a lat long of 55, -160,
leaving the default Specific Time that comes up when I click the radio
button,
have clicked Wind_direction and Wind_speed under 'with Vertical Levels'
and chosen csv as the output
and yet the returned text is this:
date,lat[unit="degrees_north"],lon[unit="degrees_east"],vertCoord[unit="m"],Wind_direction_from_which_blowing[unit="degrees"],Wind_speed[unit="m
s-1"]
2007-08-13T06:00:00Z,0.0,0.0,0.0,NaN,NaN
If I query the U and V components, it's a little better, although I only
get one line of data, not an entire sounding through the pressure levels.
Can anyone tell me what I am doing wrong?
Also, the data getting returned are just the data stored at the nearest
grid node, correct? There isn't any interpolation going on is there? If
not, how would I query the 4 nearest grid nodes for a location so that I
could do an interpolation?
Thanks much for any suggestions
Evan
