Table 3. Simulated and experimental subepidermal gas concentrations skin of pears for different ambient conditions.

Condition		Ambient Atmosphere
		20.8% O2, 0% CO2		20.8% O2, 0% CO2		0% O2, 0% CO2
		T = 20°C		T = 1°C		T = 20°C
		O2 (kPa)	CO2 (kPa)	O2 (kPa)	CO2 (kPa)	O2 (kPa)	CO2 (kPa)
Measurement		14.7^a	4.8^a	20.7^a	0.6^a	0.2^a	4^a
σ_experiment		1.0^a	1.1^a	0.2^a	0.27^a	0.071^a	0.36^a
Model	Surface	20.8	0	20.8	0	0	0
	Mean	14	4.7	19.3	0.59	0	4.4
	Subepidermal	9.7	7.7	18.6	0.97	0	7.1

The concentration at the outer surface of the fruit, just beneath the epidermis and the mean of both is reported. There is a good correspondence between the mean predicted concentrations and the measured ones. σ denotes the standard deviation.
