If the flight wraps around midnight, times past midnight should be greater The time frame may also be changed in the time-series plots via the To whatever amount of time is remaining in the file. Time frame length until End-of-File is reached then the time frame may change PgFwd and PgBkd buttons exist to facilitate moving through theįile in a sequential manner. New time frames may be entered in the Time Period areaĪt the top of the Variable Selection window, and then pressing Apply.

Number is stored in the header of the netCDF file and can be viewed from Will look for the file /home/local/proj/130/landmarks. Looking at data from ACE-1, (which is project number 130), then ncplot If PROJ_DIR points to /home/local/proj, and you are The environment variable PROJ_DIR to locate WINDS landmarksįile. The Landmarks button on the track window looks in the directory defined by Ncplot uses, though it is not required, a shell environment variableĬalled DATA_DIR as the default directory to locate data files. Specifically it is developedĪnd maintained on Redhat Enterprise Linux 7. Environment ncplot is written in C, requiring X11/R6 and Motif 1.2 (or later),Īnd the netCDF library 3.0 or later. Getting Started Acquiring ncplot is available at. Has been made to make it "what you see is what you get" between the screen ncplot will plot variables ofĭiffering rates (and from different files) next to each other. Ncplot is NOT for contouring, image or vector data.Ĭenter for Atmospheric Research to view and analyze our aircraft dataĬonventions were designed to store multi-rate data, i.e., variable A may be Publication quality PostScript printouts.Allows user-defined titles, labels, scaling, and major & minor tic marks.Spectra, Co-spectra, Quadrature, Coherence, and Phase.Can draw from up to 4 netCDF files on the same plot.Both Low-rate and Mixed-rate files are supported, as well asįiles where the data have been reduced below 1 sps (sample per second), e.g., ncplot allows the user to view time-series data stored inĬonventions.
