The AGGI is an index that provides an easily understood and scientifically
unambiguous point of comparison for tracking annual changes in levels of
atmospheric greenhouse gases.
The AGGI is based on the analyses of atmospheric levels of all the major
and minor long-lived greenhouse gases, and factors in the relative strengths
of each gas in its ability to trap heat.

The ODGI is an index that relates changes in atmospheric amounts of ozone
depleting gases and the recovery of the stratospheric ozone layer.
The ODGI is a number between 0 and 100 indicating the amount of ozone-depleting
chlorine and bromine in the atmosphere relative to the peak observed (ODGI = 100)
and the amount at which recovery is expected (ODGI = 0).

CarbonTracker is a tool designed to keep track of time dependent emissions and
uptake of atmospheric carbon dioxide (CO2), both natural
and manmade. CarbonTracker is a global system, but the emphasis is on North
America where we currently most closely monitor atmospheric CO2.
We expect to update CarbonTracker once a year, with results through the end of the
previous year. The atmospheric CO2 data is still very
sparse, and we invite additional organizations to join and make this an evolving
community project by bringing in new data and model improvements.

The GLOBALVIEW data products are designed to enhance the spatial and temporal
distribution of atmospheric observations of CO2, CH4
and other related greenhouse gases. GLOBALVIEW products are specifically
intended as tools for use in carbon cycle modeling studies.
