Sodium lidar data for 'The airglow emission layer altitude cannot be determined unambiguously from temperature comparison with lidars'
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'The data consist of 42 nightly mean temperature profiles and the corresponding standard error. Several additional variables contain supplementary information, such as the beam number (either 0 or 1) in use and the azimuth and zenith angle this beam pointed to. Date and time are stored as Julian date. All data are stored in a NetCDF4 file' .
