Without question, I would welcome a more rigorous approach or an explanation why the GEOS-5 model produces the data that it does.ДЇrom 04:30 UTC, this adjustment is no longer necessary because GEOS-5 appears to have been upgraded. This is not scientifically valid, but it does allow the visualization to become illustrative of the discussion occurring today around atmospheric CO 2. To bring the GEOS-5 results closer to contemporary numbers, I have added a uniform offset of +32 ppmv, increasing the global mean to 400 ppmv. GEOS-5 was constructed in the 2000s, so perhaps the model does not account for accumulation of atmospheric CO 2 over time? This is simply speculation. For example, from the run at 00:00 UTC, the global mean is only 368 ppmv whereas CO 2 observatories report concentrations closer to 400 ppmv. While implementing the visualization of CO 2 surface concentration, I noticed the NASA GEOS-5 model reports a global mean concentration that differs significantly from widely reported numbers. This layer can be interpreted as the thickness of smoke from wildfires and other sources of combustion.ДЄbout CO 2 concentrations for dates earlier than 04:30 UTC The aerosol optical thickness (AOT) of light at 550 nm due to organic matter suspended in air.
