"Method ref": "CH02L_aethalometer",
"Standard method": "SOP=GAW227",
"Inlet type": "Hat or hood",
"Inlet description": "Heated total aerosol inlet (25 degC), collects aerosols and hydrometeors smaller than 40 micrometers",
"Humidity/temperature control": "Temperature conditioning at 25 deg. C",
"Humidity/temperature control description": "Sample dried to below 20% RH due to the heated inlet",

"Volume std. pressure": "1013.25 hPa",
"Detection limit": "5.0 1/Mm",
"Detection limit expl.": "Determined by instrument noise characteristics, no detection limit flag used",
"Measurement uncertainty expl.": "Intercomparisons with thermo-optical analysis have shown an uncertainty of a factor 2 regardless specific absorption cross-section assumed. Depends mostly on the multiple scattering correction (not used in raw data)",
"Zero/negative values code": "Zero/negative possible",
"Zero/negative values": "zero and neg. values may appear due to statistical variations and substraction of two very close measurements at very low concentrations",
