摘要: A tunable dye laser, operating between 4400 and 4500 A, was used to monitor NO2 concentrations in a sample chamber 365 m away. The atmosphere front of behind the acted as distributed reflector send laser light back through receiver near laser. measurements agreed well with situ measurements. single pair pulses allowed determination an uncertainty equivalent 0.05 km ppm.
