6-hourly global SO2 data from LHexp Raikoke eruption June 2019

Title 6-hourly global SO2 data from LHexp Raikoke eruption June 2019
Description Layer height experiment for a series of SO2 assimilation tests for the 2019 Raikoke eruption with the CAMS system which assess the impact of assimilating SO2 layer height data (V3.1 FP_ILM). In LHexp (hgze) SO2 Layer Height data produced with FP_ILM (V3.1) were assimilated with SO2 background error standard deviation values of 0.7e-7 kg/kg and horizontal background error correlation length scale of 100 km.
