Times of calculated overlap functions #123

Closed martin-rdz closed 1 year ago

martin-rdz commented 2 years ago

Is the overlap function calculated at each profile?

When looking at the output, I can only find one overlap file for each 6-hour period, e.g.,

/data/level1a/polly/PollyXT_LACROS/2020/08/20/2020_08_20_Thu_LACROS_00_00_01_overlap.nc
/data/level1a/polly/PollyXT_LACROS/2020/08/20/2020_08_20_Thu_LACROS_06_00_01_overlap.nc
/data/level1a/polly/PollyXT_LACROS/2020/08/20/2020_08_20_Thu_LACROS_12_00_01_overlap.nc
/data/level1a/polly/PollyXT_LACROS/2020/08/20/2020_08_20_Thu_LACROS_18_00_01_overlap.nc

In case the overlap is calculated per profile, would it make more sense to also store it in the profile netcdfs? Or at least in a extra netcdf similar to the profiles?

Timestamps has been inserted to the overlap files. In addition, the overlap function has been converted to a 2-dimension array (time x height) with the length of the dimension of time to be 1. I've enclosed a file as an example of the new overlap file (see the link below).

Hope this issue can be closed.
