THD Site Data

CO2 Climatology CO2 Time Series
Figure 1: Annual Climatology is a compilation of all Carbon Dioxide (CO2) time series data that has been collected with the Mauna Loa (MLO) trend removed. The Historical profile includes every CO2 measurement (excluding flagged data) for each month, at each altitude and has been binned to get the monthly average.


CO Climatology CO Time Series
Figure 2: Annual Climatology is a compilation of all Carbon Monoxide (CO) time series data that has been collected with the Mauna Loa (MLO) trend removed. The Historical profile includes every CO measurement (excluding flagged data) for each month, at each altitude and has been binned to get the monthly average.


SF6 Climatology SF6 Time Series
Figure 3: Annual Climatology is a compilation of all Sulfur Hexafluoride (SF6) time series data that has been collected with the Mauna Loa (MLO) trend removed. The Historical profile includes every SF6 measurement (excluding flagged data) for each month, at each altitude and has been binned to get the monthly average.


CH4 Climatology CH4 Time Series
Figure 4: Annual Climatology is a compilation of all Methane (CH4) time series data that has been collected with the Mauna Loa (MLO) trend removed. The Historical profile includes every CH4 measurement (excluding flagged data) for each month, at each altitude and has been binned to get the monthly average.


N2O Climatology N2O Time Series
Figure 5: Annual Climatology is a compilation of all Nitrous Oxide (N2O) time series data that has been collected with the Mauna Loa (MLO) trend removed. The Historical profile includes every N2O measurement (excluding flagged data) for each month, at each altitude and has been binned to get the monthly average.
