This page provides a brief overview of the functions avaliable in Eubrewnet to determine Brewer configuration parameters.

: input data used, available options are o3l15
(default if the option is not passed in the url), o3l15v2
, o3l1
, sco3
for the O3L1.5, O3L1.5V2, O3L1 and sun scan measurements, respectively. For the sco3
option, the step
option with the value of the micrometer step must be also passed in the url. Individual observation (not summaries) are used in all cases. Note you can override the default configuration used to process the data in Eubrewnet using the urlconfig
method (eg, to pass new ETC filter correction methods add &urlconfig&fc=1,2,3,4,5
to the url)calc
: calculation to perform, available options are etc
(Langley-plot with all the data, default option), filters
(the Langley-plot fit is done using dummy variables for filters 3, 4, 5, and thus allows to determine the ETC filter correction of those filters with respect to the ETC obtained for the set measurements with filters 0, 1, and 2), and filters_etc
(this option performs two fits: first, a filters
run to determine the ETC filter corrections, and then an etc
calculation using these ETC filter corrections). For etc
runs, two different fits are performed: ms9
vs airmass
(brewer method) and ms9/airmass
vs 1/airmass
(dobson method)minairmass
: airmass minimum in etc
calculations (defaults to 1.70 if the option is not passed in the url)maxairmass
: airmass maximum in etc

: minimum number of observations in the half-day to perform the Langley in etc
calculations (default value: 25)filters_minairmass
: airmass minimum in filters
calculations (defaults to 1 if the option is not passed in the url)filters_maxairmass
: airmass maximum in filters

: minimum number of observations in the half-day to perform the Langley in filters

: don't perform the langley if the maximum of the standard deviation of the half-day ozone is above this value (default: 2.5)minrsquared
: don't accept the langley results if the r2 of the fits are below this value (default: 0.999)date
