An Assessment of Pseudo-Operational Ground-Based Light Detection and Ranging Sensors to Determine the Boundary-Layer Structure in the Coastal Atmosphere

Table 3

Mean statistical parameters of the ALS300-CHM15K-CL31 versus radiosounding (RS) comparison. For each 𝑋 versus 𝑌 comparison, 𝑅 is the correlation coefficient, bias = abs (𝑌-𝑋), Sigma = std (𝑌-𝑋), and consistency is percentage of 𝑋 versus 𝑌 detections closer than 200 m, that is, abs (𝑌-𝑋)≤200 m.

Comparison (SML)	𝑅	Bias (m a.g.l.)	Sigma (m a.g.l.)	Consistency (%)	Num. of samples
ALS300 versus RS	0.91	150.6	175.1	75.0	16
CL31 versus RS	0.74	218.2	233.4	36.4	11
CHM15K versus RS	0.88	177.2	191.6	64.7	17
Comparison (DRCL)	𝑅	Bias (m a.g.l.)	Sigma (m a.g.l.)	Consistency
ALS300 versus RS	0.92	148.5	207.3	61.5	13
CL31 versus RS	0.61	143.4	142.9	62.5	8
CHM15K versus RS	0.81	192.1	235.8	53.3	15
