MONTHLY CARBON DIOXIDE READINGS AT SOUTH POLE 1/58 TO 1/87 JIM ELKINS (NOAA) FTS 320-6224 JIM'S NAME FOR FILE = CO2SPO.DAT NUMBER OF OBSERVATIONS = 349 RESPONSE VARIABLE = MEAN CARBON DIOXIDE CONCENTRATION (IN PARTS PER MILLION) ORDER OF VARIABLES ON A LINE IMAGE-- 1. YEAR (1958 TO 1987) 2. MONTH (1 TO 12) 3. MEAN (OVER THE MONTH) CARBON DIOXIDE CONCENTRATION (PPM) NOTE--A ZERO RESPONSE MEANS NO READING AVAILABLE. NOTE--FROM 1973 ONWARD, THE RAW DATA POINTS WERE HOURLY AND SO THE REPORTED MONTHLY AVERAGES CONSISTED OF ABOUT 720 OBSERVATIONS. PRE-1973, THE RAW DATA WAS SPARSE, SOMETIMES ONLY ONE READING PER MONTH. NOTE--POLLUTION = COMBINATION OF HIGH CO2 AND HIGH FREON WHEN FREON HIGH, EXPECT HIGH CO2 (POLLUTION) CO2 COMES FROM COMBUSITON OF FOSSIL FUELS FREON COME FROM AIR CONDITIONS AT MOST SITES, THERE SHOULD BE A SEASONAL EFFECT FOR CO2 AT POINT BARROW, THERE IS ALSO A SEASONAL EFFECT FOR FREON-11 QUESTIONS-- TRENDS AND CYCLES OVER TIME? RELATIONSHIP BETWEEN FREON AND WATER VAPOR? RELATIONSHIP BETWEEN FREON AND CO2? SAME PATTERNS AT ALL 5 SITES? 1958 01 000.00 1958 02 000.00 1958 03 314.31 1958 04 000.00 1958 05 000.00 1958 06 314.66 1958 07 000.00 1958 08 000.00 1958 09 315.41 1958 10 000.00 1958 11 000.00 1958
