[gradsusr] [non-nasa source] Re: Plotting daily average

Hi, Emily -- 
Remove 'lon' from your XDEF entry, remove 'lat' from your YDEF entry, and remove 'time' from your TDEF entry. You will need to add entries 'ZDEF 1 linear 1 1' and 'UNDEF -9.99e8 and also a variable declaration 'varname 0 99 var description'. Then use the 'open' command instead of 'xdfopen'.

    Hi Jennifer,

    I have a couple questions about your approach to create the daily means. I created a script that would create the daily means for all days in 2018, but I am unsure how to use the dailymean.dat file when creating the plot. I tried adding the .dat file to a ctl file, but I received the following error message: 

    "Error: nc_open failed to open file /nfs3m/archive/sfa_cache04/users/g00/esaunde2/grads_scripts/scripts/GEOS_CF_Total/All_Species/dailymean_totcolco_2018.dat
    NetCDF: Unknown file format
    gadsdf: Couldn't ingest SDF metadata.
    SDF Descriptor file GEOS_CF_hindcast_tavg1_2d_xgc_Nx_daily_totcolco.ctl was not successfully opened & parsed."

    Here is the format of the ctl file including the .dat file 
    "Dset/nfs3m/archive/sfa_cache04/users/g00/esaunde2/grads_scripts/scripts/GEOS_CF_Total/All_Species/dailymean_totcolco_2018.dat
    TITLE Daily Mean totcol_co Jan012018
    XDEF lon 1440 LINEAR -180.0 0.25
    YDEF lat 721 LINEAR  -90.0 0.25
    TDEF time 9000 LINEAR 00:30z01JAN2018 1hr"
    Is there a particular format to use when adding a .dat file to a ctl file or do I have to convert the .dat file to a netcdf format. 
    Thanks for your help in advance.

    Emily

        Hi, Emily -- 
        If you want to convert a dataset that is hourly to one that is daily, you need to use fwrite (or sdfwrite) to build it explicitly. This is a bare-bones outline for what you need to do, my syntax is not guaranteed to work:

        tbeg=1
        tend=365
        'set t 'tbeg' 'tend
        areaavg = tloop(aave(var,g))   ;* define your hourly area average time series first, so you do the I/O only once
        'set fwrite -ap dailymean.dat' 
        '!/bin/rm -f dailymean.dat'    ;* make sure that dailymean.dat does not already exist
        'set gxout fwrite'
        t=tbeg
        while (t<tend)
           'set t 't
           'd ave(areaavg,t+0,t+23)    ;* this is the daily mean 
           t=t+24
        endwhile
        'disable fwrite'

            Hi all,

            I need some help plotting the daily average for the total CO burden. In 
            my script I am trying to plot the calculated Total CO burden daily 
            average and plot the daily average value for each day, but instead it 
            plots the value for each hour instead of the average of the hours. Here 
            is part of the script I am working with:

            'set time 01JAN2019
            'set time 05JAN2019
            'set z 1'
            'set lon 0'
            'set lat 0'
            'set ccolor 14'
            'set cstyle 1'
            'set cthick 10'
            'cons = 2.687e+20/6.022e+23*48/1.0e+12'
            'define tseries = 
            cons*aave(totcol_co,lon=0,lon=360,lat=-90,lat=90)*510.1*1000000000000'
            'define a = ave(tseries, time=00:30z01JAN2019, time=23:30z05JAN2019)'
            'set parea 1.5 9 1.5 7.5'
            'set digsiz 0.10'
            'set cmark 3'
            'd a'

            Thank you for your help in advance.
