Description: | The data from the Nauru MFRSR is questionable because either the cosine correction
is bad and/or the head was not level. These problems cause some total optical
depths to be below the Rayleigh limit ... obviously something is wrong! The
head was checked for level on 1999/05/12 and it was found to be out of level
so we do know that 'levelness' has been a problem. We don't yet know if the
cosine correction, too, has been a problem. In any event the head was
changed on 99/06/19 and the data from this point on looks very good. |
