[ncl-talk] Plot csv file

[Dennis Shea]

Hi Anahita

This is *temporarily *offline.

This looks like grid point data that was written to a CSV (ascii/text) file.
Do you know the sizes (nlat,mlon) of the array?

Also, it looks to me like the lat/lon locations should  have been written
as double precision.
Successive points are separated by numbers on the order of e-6.


ncol = 5
ana  = readAsciiTable("Book4.csv", ncol, "double", 1)
lon1 = ana(:,0)
lat1 = ana(:,1)
no   = ana(:,2)
no2  = ana(:,3)
bc   = ana(:,4)

N    = dimsizes(lon1)   ; # of points
print("N="+N)
print("-----")
printMinMax(lon1,0)
printMinMax(lat1,0)
print("-----")


no at long_name = "NO"
no at units     = "?"
no2 at long_name= "NO2"
no2 at units    = "?"
bc at long_name = "BC"
bc at units     = "?"

printMinMax(no ,0)
printMinMax(no2,0)
printMinMax(bc ,0)
print("=====")
print((lon1(1:)-lon1(:N-2))+"     "+(lat1(1:)-lat1(:N-2)))  ; differences
print("-----")
