What is the Mauna Loa data?
Mauna Loa Observatory is a station that measures elements in the atmosphere that contribute to climate change on Earth. They also measure elements that may deplete the ozone layer. This data is critical because the ozone layer protects us from harmful radiation produced by the sun’s ultraviolet rays.
Where do we get the longest continuous record of carbon dioxide concentrations?
Mauna Loa
The Mauna Loa Carbon Dioxide Record is the longest continuous record of atmospheric concentrations of carbon dioxide, the chief greenhouse gas responsible for global climate warming.
What is a temperature anomaly graph?
A temperature anomaly is the difference from an average, or baseline, temperature. A positive anomaly indicates the observed temperature was warmer than the baseline, while a negative anomaly indicates the observed temperature was cooler than the baseline.
Why do we use temperature anomalies?
Anomalies more accurately describe climate variability over larger areas than absolute temperatures do, and they give a frame of reference that allows more meaningful comparisons between locations and more accurate calculations of temperature trends.
How do you cite Mauna Loa data?
To cite a particular archive version, include both the DOI and the archive date in the citation. A suggested citation is displayed in the component metadata for each archive. Atmospheric in situ monthly CO2 data set taken at Mauna Loa, Observatory, Hawaii: Latitude 19.5°N, Longitude 155.6°W, Elevation 3397m.
How do you get to Mauna Loa?
Both are accessible by one-lane paved roads. Neither has public telephones or public transportation. It takes about an hour to drive from the Kilauea Visitor Center via Mauna Loa Road to the trailhead, and two hours to drive to the Observatory trailhead via Saddle Road.
Which 2 places do we have the best and longest set of data on CO2 in the earth’s atmosphere?
The CO2 data from Mauna Loa Observatory is the world’s longest series of direct CO2 measurements. In 1958, David Keeling from Scripps Institution of Oceanography first set up instruments at the top of this Hawai’ian volcano in the middle of the Pacific.
Which human activity is our biggest source of carbon dioxide?
burning fossil fuels
Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation.
