The table also shows changes in GPP (AGPP), total ecosystem respiration (ATER), and NEE (???? for both July-September and for the whole year. (The more positive GPP and NEE are, the larger is the carbon uptake from the atmosphere. For the July to September period, units are in g C m2 month-1, for the annual period in g C m2 year1. The more positive TER is, the larger is the carbon release. Changes in climate and CO2 fluxes are reported for the averaging period of July to September and for the whole year. The vegetation is coded according to the IGBP classification: ENF, evergreen needle-leaf forest, EBF, evergreen broad-leaf forest; DBF, deciduous broad-leaf forest, GRA, grassland, MF, mixed forest, OSH, open shrubland.) * Standard error (s.e.) estimates for the changes ?GPP and ?TER (see Methods for details). t Non-reported values with more than 20% non-reliably filled gaps in 2002 or 2003 Question 1 Calculate the mean changes in temperature, precipitation, GPP, TER, and NEE between 2002 and 2003 by summing values for all locations and dividing by 14 (the number of locations). Use the July through September values for your calculations. What can you conclude about changes in temperature, rainfall, and changes in CO2 in the ecosystem from these numbers?Explanation / Answer
1) as per given hint in this question,
By adding all the temperature values of all the location and then dividing by 14 will give us 1. 9643 0C
same way, for precipitation value is - 31. 9286 mm
for GPP, value is - 43. 0714
For TER, value is - 25. 0714
For NEE, value is - 18. 00
From temperature values it seems to be an normal temperature change
From GPP and NEE, the carbon uptake is less. It means carbon is taking by trees are very less because ( see the reason in TER)
From TER, the carbon release is less which is indicative parameter of less burning of fuel, factory smoke etc.
Hence from all above points it is concluded that there is very less CO2 into atmosphere.
2) here the NEE values are negative indicate that there is very less carbon taking from atmosphere it means there is very less carbon in the atmosphere hence drought type condition will not be there. Because for drought, the CO2 is responsible but it is released when there is burning of fuels, release of factory smoke, which is not happening It is seen from all above parameters.
