Dear R Users,
If a variable, say CO2(ppm), is varying with time. Then how to calculate CO2
(ppm) growth rate /a-1
I have CO2 time series (1991-2000), as:
time, year, month, day, hour, min, sec, lat, long, height, CO2
1991.476722 1991 6 24 0 5 0 -38.93 145.15 4270 353.680
1991.476741 1991 6 24 0 15 0 -39.20 145.22 4270 353.950
1991.476747 1991 6 24 0 18 0 -39.43 145.28 4270 353.510
-----------------------------------------------
2000.740788 2000 9 28 3 5 0 -38.00 145.00 2280 366.750
2000.740794 2000 9 28 3 8 0 -38.00 145.00 1830 366.550
2000.740803 2000 9 28 3 13 0 -38.00 145.00 1220 370.550
