trajectory data (gdas1)

Post by nels8915 »

Hi,

I am using the package PySPLIT to generate trajectories and moisture flux with HYSPLIT, but I am running into issues with my trajectory data's specific humidity. When I view what information a single trajectory has in the HYSPLIT program, the only column labeled is PRESSURE, not the RELHUMID or SPCHUMID columns, for example. Also, all values in the seventh column are 0. I think this is where my specific humidity error is coming from in PySPLIT, and I was wondering if you see any issue here? Here's the beginning portion of a trajectory file:

8 1
GDAS 13 6 22 0 0
GDAS 13 6 29 0 0
GDAS 13 7 1 0 0
GDAS 13 7 8 0 0
GDAS 13 7 15 0 0
GDAS 13 7 22 0 0
GDAS 13 7 29 0 0
GDAS 13 8 1 0 0
1 BACKWARD OMEGA
13 7 2 17 32.060 118.800 500.0
1 PRESSURE
1 1 13 7 2 17 0 1 0.0 32.060 118.800 500.0 943.7
1 1 13 7 2 16 0 2 -1.0 31.763 118.331 548.7 938.7
1 1 13 7 2 15 0 3 -2.0 31.431 117.909 598.7 932.8
1 1 13 7 2 14 0 2 -3.0 31.043 117.515 653.7 927.3
1 1 13 7 2 13 0 1 -4.0 30.600 117.135 728.7 910.0
1 1 13 7 2 12 0 0 -5.0 30.162 116.788 775.6 896.6
1 1 13 7 2 11 0 1 -6.0 29.770 116.511 795.3 906.3
1 1 13 7 2 10 0 2 -7.0 29.417 116.300 838.5 910.7
1 1 13 7 2 9 0 3 -8.0 29.075 116.117 958.6 903.2
1 1 13 7 2 8 0 2 -9.0 28.724 115.924 1118.8 878.0
