MAO/ACSM/S1 - Reprocess: Aerosol chemical speciation monitor errors in data

The data will be reprocessed with the manufacturer's software to correct for collection 
efficiencies and instrument response.  The data in the current form is incorrect and should 
not be used.

Data reprocessing is underway. Please use maoaosacsmS1.b1 instead until the 
reprocessing data of maoaosacsmS1.a1 is ready.

• Mass concentration of ammonium, ambient aerosol in air(ammonium)
• Mass concentration of sulfate, ambient aerosol in air.(sulfate)
• Mass concentration of nitrate, ambient aerosol in air(nitrate)
• Mass concentration of total organics, ambient aerosol in air(total_organics)
• Mass concentration of chloride, ambient aerosol in air.(chloride)
