Organic and elemental carbon (OC and EC) are operationally-defined by the measurement process, so long-term trends may be interrupted with instrumentation changes. A modification to the U.S. IMPROVE carbon analysis protocol and hardware is examined t

Thermally derived carbon fractions including organic carbon (OC) and elemental carbon (EC) have been reported for the U.S. Interagency Monitoring of PROtected Visual Environments (IMPROVE) network since 1987 and have been found useful in source appor

The thermal/optical method has been widely used for quantifying total carbon (TC), organic carbon (OC), and elemental carbon (EC) content in ambient and source particulate samples. Thermally defined carbon fractions have been used for source identifi
