BADC Trajectories - Plotting Help

For help on an individual item on the form, simply click on the link from the descriptive text or scroll down this window until you have found the relevant section.

Download NetCDF file:: Use this to download the output file from the integration. The output file is a netcdf file and has the extension .nc. Provided the browser has no application type set for .nc files you will be prompted for a file name for the NetCDF file.
View NASA Ames file:: Use this link to view a NASA Ames dump of the trajectory file. To Download the file use 'Save As' on your browser. The suggested file name for NASA Ames trajectory files is ttyymmdd.hha. Where 'tt' is the text string 'tt', 'yy' is the year, 'mm' the month, 'dd' the day of the month, 'hh' the hour (all of the start time for the trajectory integration), and 'a' a letter used to designate different files produced for the same initial time.
Plot type:: These are a list of the plot types avaliable from the output file. At present the Lat-Lon Map is a cylindrical projection. It is possible to make multiple selections of the plot type.
Trajectory initial conditions:: Choose which trajectories you would like plotting using the initial conditions of the trajectory points. Multiple selections can be made if you want more than one trajectory on a single plot. If only one trajectory is present it will be plotted by default; there is no need to select it.
Plot Limits:: Set the minimum and maximum that will appear on the plot using the plot limits. If no limits are filled in for a variable then defaults will be chosen. Occasionally if you fill in only one limit it will have apparently no effect. Fill in both maximum and minimum guarantees the limits will be used.
Markers:: This option lets you plot markers regular intervals along the trajectories on the lat-lon maps. The markers are off by default, selecting the check box will turn them on. Use the Frequency to determine the interval at which the markers are plotted.
Output to:: The default ouput is to the browser. You can select to output to a postscript file. If the browser has an application such as ghostview set for postscript files, then this application will be launched. Otherwise you will be prompted for a file name for the postscript file.
