Data Products and Visualization
Annual Greenhouse Gas Index
The AGGI index that provides a point of comparison for tracking annual changes in levels of atmospheric greenhouse gases.
Ozone Depleting Gas Index
The ODGI is an index that relates changes in atmospheric amounts of ozone depleting gases and the recovery of the stratospheric ozone layer.
FTP Data Finder
Search for and download datasets available on the GMD public FTP server.
Current Trends in CO2
View graphs and get data for the most recent CO2 atmospheric data at Mauna Loa, Hawaii and for global averages.
Interactive Atmospheric Data Visualization
A data exploration tool for GMD measurements.
Solar Calculator
Generate estimates for sunrise, sunset, solar noon and the position of the sun in the sky for a desired location and date.
GLOBALVIEW
The GLOBALVIEW data products enhance the spatial and temporal distribution of atmospheric observations of CO2, CH4 and other related greenhouse gases.
CarbonTracker
CarbonTracker is a tool designed to keep track of time dependent emissions and uptake of atmospheric carbon dioxide (CO2), both natural and manmade.
Ozone and Water Vapor
View data of the South Pole Ozone hole, plus profiles of ozone from Greenland, and water vapor from Boulder.
Trace Gases
View graphs from the CATS trace gas measurement system.
Radiation
View plots of various types of solar radiation measurements from around the globe.
Aerosols
Plots of measured aersol properties.
Atmospheric Transport
View back trajectories from some of the global GMD observations sites using the ESRL/GMD IADV web app.
Calibrations of Reference Gases
Results of CO2 and CH4 calibrations on reference gas tanks used for atmospheric measurements.
