Convective influence trajectory plots

README file notes for NASA ARC convection products:

This product plots the positions of air parcels in the DCOTSS region at the given altitude that have been influenced by convection in the past 7 days. It also plots the locations of the convection and trajectories between the convection and the influenced air parcels.
Cloud top altitudes up to ~1.5 to 2 days before the current date are estimated using global TRMM/GPM rainfall, global brightness temperatures, GFS temperature profiles, and GFS tropopause temperatures and pressures.
Cloud top altitudes from ~1.5 days before the current date to ~6 hours before the current time are derived from LARC cloud products.
Cloud top altitudes from ~6 hours before the current time up to ~3 days ahead of the current date are derived from GFS forecast convective rainfall and GFS high cloud top pressures.
The 4 sets of plots (current day, day +1, day +2, day +3) are available by 3 AM Pacific time each morning.
The file name convention is as follows: "dcotss_(yymmddhh)_NMC_50_53_58_cldhist_traj_(alt)kft.pdf"
- yymmddhh: date (year, month, day, hour) from which backward trajectories of air parcels in the boxed region are calculated
- alt: altitude (kft) from which the backward trajectories of air parcels in the boxed region are calculated
For example, the file name convention for plots of the trajectories launched on the current date on June 9, 2020 at 18Z is as follows:
- dcotss_20060918_NMC_50_53_58_cldhist_traj_50kft.pdf
- dcotss_20060918_NMC_50_53_58_cldhist_traj_53kft.pdf
- dcotss_20060918_NMC_50_53_58_cldhist_traj_58kft.pdf
