A Comparison of Three Gap Filling Techniques for Eddy Covariance Net Carbon Fluxes in Short Vegetation Ecosystems

Table 1

Percentages of original gaps in NEE measurements.

Flux site	Daytime		Nighttime		All time
		Gap (%)		Gap (%)		Gap (%)
Marsh site	4583	18.4%	2953	36.2%	7536	25.4%
Rice site	4804	12.4%	3212	26.7%	8016	18.2%
Soybean site	4804	15.0%	3212	28.7%	8016	20.5%

The is the total number of data for daytime, nighttime, and all the time. The % is the percentage of gaps for daytime, nighttime, or all the time.
