Since 1958 scientists have collected daily air samples at an observatory on the Mauna Loa volcano in Hawai. One particularly important gas is carbon dioxide (COz). While the concentration of COz is very small (typically measured in parts per million, ppm), it has a very important effect on climate Atmospheric CO, at Mauna Loa Observatory 40아 Scripps Institution of Oceanography NOAA Earth System Research Laboratory 380 1960 1970 1980 1990 2000 2010 YEAR rnd The 57 year record of Co, measurements is shown in Figure 1.

Since 1958 scientists have collected daily air samples at an observatory on the Mauna Loa volcano in Hawaii. One particularly important gas is carbon dioxide (CO_2). While the concentration of CO_2 is very small (typically measured in parts per million, ppm), it has a very important effect on climate. The 57 year record of CO_2 measurements is shown in Figure 1. The figure contains two graphs. The red line is uncorrected data. It shows short-period oscillations between highs and lows superimposed on an increasing trend. The black line shows the corrected data after the short period oscillations have been removed. Investigate the source of the short-period oscillations shown in the red graph. Select a 10-year period and count the number of highs (e.g. the cycles) within that period. Number of highs: _______. Based on your observations of the number of cycles within a 10 year period, propose a cause of the oscillations.

Expert Answer

Answer

Red line Count the oscillation period between a period of 10 years, for every oscillation 1 high is to be considered. From the graph data shows

For a 10 year period number of highs = 10
