CF metadata,
I?m currently working on a dataset that has a suite of variables with two different averaging periods. Going through the archives I can?t find any discussions of this type. For example one variable measures average temperature each minute while a second variable measures average pressure over the preceding 5 minutes (essentially a running box car mean with overlapping samples.) The time step is the same for both variables. Is there a way to list two different time bounds variables associated with the same time step?
I was thinking of something like this:
dimensions:
time = UNLIMITED; // (1440 currently)
nv = 2;
variables:
float temperature(time);
temperature:long_name = ?Atmospheric temperature";
temperature:units = ?degC";
temperature:cell_methods = "time: mean";
float pressure(time);
pressure:long_name = ?Atmospheric pressure over preceding 5 minutes";
pressure:units = ?hPa";
pressure:cell_methods = "time: mean?;
pressure:bounds = "time_bnds2";
double time(time);
time:long_name = "time";
time:units = ?minutes since 1998-04-19 06:00:00 0:00";
time:bounds = "time_bnds1";
double time_bnds1(time,nv);
double time_bnds2(time,nv);
data:
time = 0., 1., 2., 3., 4. ...;
time_bnds1 = -1,0, 0,1, 1,2, 2,3, 3,4 ...;
time_bnds2 = -5,0, -4,1, -3,2, -2,3, -1,4 ...;
Thanks,
Ken
