Rename VII readers and update VII readers for new test data
It has been pointed out that the VII L1b reader no longer works for the publicly available test data, but also doesn't work for the newest EUMETSAT internal test data. The reader needs updates to work for the future versions of the data files.
Additionally, the "VII" name is discontinued and "METimage" should be used instead. This would mean the new reader names should be "metimage_l1b_nc" and "metimage_l2_nc" and the old names deprecated (see these dictionaries).
I'm assigning this to Andrea, but understand that other EUMETSAT employees may be doing the work.
Completing this work will also close my related Polar2Grid issue: https://github.com/ssec/polar2grid/issues/767
I also marked this as "pre-launch" even though technically things are launched, but they aren't operational.
In satpy/readers/vii_base_nc.py:216 The start/end_time format need to be modified to fit latest L1B global attribute (%Y-%m-%dT%H:%M:%S.%f) as such:
@property
def start_time(self):
"""Get observation start time."""
try:
start_time = dt.datetime.strptime(self["/attr/sensing_start_time_utc"], "%Y-%m-%dT%H:%M:%S.%f")
except ValueError:
try:
start_time = dt.datetime.strptime(self["/attr/sensing_start_time_utc"], "%Y%m%d%H%M%S.%f")
except ValueError:
start_time = dt.datetime.strptime(self["/attr/sensing_start_time_utc"], "%Y-%m-%d %H:%M:%S.%f")
return start_time
@property
def end_time(self):
"""Get observation end time."""
try:
end_time = dt.datetime.strptime(self["/attr/sensing_end_time_utc"], "%Y-%m-%dT%H:%M:%S.%f")
except ValueError:
try:
end_time = dt.datetime.strptime(self["/attr/sensing_end_time_utc"], "%Y%m%d%H%M%S.%f")
except ValueError:
end_time = dt.datetime.strptime(self["/attr/sensing_end_time_utc"], "%Y-%m-%d %H:%M:%S.%f")
return end_time
