NASA Global Temperature Anomaly dataset contains the change in global surface temperature relative to 1951-1980 average temperatures. This research is broadly consistent with similar constructions prepared by the Climatic Research Unit and the National Oceanic and Atmospheric Administration.

Ozone is a gas made up of three oxygen atoms (O3). It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Ozone protects life on Earth from the Sun’s ultraviolet (UV) radiation. In the lower atmosphere (the troposphere) near the Earth’s surface, ozone is created by chemical reactions between air pollutants from vehicle exhaust, gasoline vapors, and other emissions. At ground level, high concentrations of ozone are toxic to people and plants.  The maximum of the daily ozone hole size and the minimum of the Southern Hemisphere daily ozone minimums for each year and the date of occurrence. Date links are to the image for the particular day. There are no data for 1995. 

Carbon dioxide (CO2) is an important heat-trapping (greenhouse) gas, which is released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions. 

The data lists the moment of mid-totality and the duration of totality for a handful of cities that lie close to the center of the path. Data from NASA.
