Short summary
Organic carbon (OC) and elemental carbon (EC) in more than 1300 Hong Kong samples were analyzed using both NIOSH TOT and IMPROVE TOR protocols. EC discrepancy between the two protocols mainly (83 %) arises from a difference in peak inert mode temperature, while the rest (17 %) is attributed to a difference in the optical method (transmittance vs. reflectance) applied for the charring correction. Two approaches are proposed to translate NIOSH TOT OC and EC data into IMPROVE TOR OC and EC data.
