[Data Error] surface temperature estimates are not useful #284

Closed dlebauer closed 4 years ago

dlebauer commented 4 years ago

Dataset

Surface temperature data have two problems

do not have time associated with measurement, so it is not possible to compute the temperature difference relative to the air temperature
integrate over soil and leaf, so the data are only useful after canopy closure.

Suggested Correction

provide time information when computing surface temperature
use a soil mask so that it actually measures leaf temperature

In the mean-time I am marking these as being checked and found to be in error. They will be excluded from public datasets until this issue is fixed.

update traits set checked = -1, 
  notes = 'two problems with surface_temperature: 1) no time is provided so it is not possible to determine air temperature and 2) the values integrate both plant and soil temperature'
 where variable_id in (select id from variables where name = 'surface_temperature');
