The Global Atmospheric Carbon Dioxide Concentration Simulation Grid Dataset (1992-2020) covers the region between 60°S and 88°N, 180°W and 180°E in 2° x 2.5° grid. The dataset was developed using an improved sinusoidal model, which was calibrated by the remotely-sensed product of troposphere CO2 concentration from 2002 to 2012 (AIRx3C2M 005) for each grid cell. Using the simulating model to retrite the data to 1992 and forecasting the data to 2020. The field-observed data of CO2 concentration was adopted to validate and analyze the accuracy of the data product. The dataset includes: (1) global dataset of monthly CO2 concentration from 1992 to 2020; (2) global dataset of annual CO2 concentration from 1992 to 2020. The dataset is archived in .nc data format, and consists of 58 data files with data size of 31.5 MB (Compressed to one single file with 23.9 MB).Browse
