DSCOVR EPIC Total Ozone

Version 01 eng
  • Abstract
    We have created an accurate data set of total column ozone, tropospheric ozone, and reflectivity from the DSCOVR EPIC instrument by implementing the latest algorithms modified from those used on Aura OMI and Suomi NPP OMPS. The results accurately capture short term synoptic changes in total column ozone driven by geochemical and geophysical processes. This can be done uniquely with EPIC from DSCOVR's vantage point where the instrument will make measurements from sunrise to sunset every 90 minutes. Accurate estimates of tropospheric ozone, which is inferred from the difference of the total column ozone and an independent measure of stratospheric column ozone, will require highly accurate total ozone retrievals.Ozone products produced from EPIC will be validated with the long term time series of ozone data from OMI and SBUV instruments. Scene Reflectivity (clouds, aerosolos, and surface) is derived as part of the ozone retrieval. The scene reflectivity in conjunction with ozone has been used to derive the amount of UV solar radiation reaching the ground. A new soft calibration technique developed based on scene matching with OMI and OMPS gives calibrated EPIC radiances. The calibrated EPIC radiances can be used to derive accurate science products from EPIC consistent with those from previous UV instruments. Retrievals of all products will be made publically available and are expected to support a wide range of scientific studies.
