Scaling of CEDS data #40

Closed JGuetschow closed 8 months ago

JGuetschow commented 2 years ago

Despite the new algorithm for scaling of early emissions data to the more recent sources the scaling of CEDS data is in some cases problematic e.g. when the CEDS data shows a strongly decreasing trend before the matching year (see e.g. Saint Lucia CH$_4$ in 1.B.1)

JGuetschow commented 8 months ago

This problem has been fixed for category 1.B.1 by changing the calculation of the trend values used for matching CEDS to the higher priority data sources for 1.B.1. We no longer calculate trend from the years preceding the matching year because these show the steep emissions decline resulting a near zero matching value and consequently a very high initial scaling factor for CEDS.
