Aerosol Absorption coefficient was measured for three wavelengths (365,520,640 nm) using a filter-based absorption photometer (Brechtel Tri-color Absorption Photometer (TAP)). There was a PM2.5 um inlet for the instrument. The reported data is at 1 minute time resolution for Jun- Sept 2022 during TRACER.
TRACER-Tethersonde, a sub-campaign of TRACER, took place during the TRACER June-September 2022 intensive operating period (IOP) at the S3 Ancillary site (29.33°N, 95.74°W) near Guy, TX. The Tethered Balloon System (TBS) operated during the first two weeks of each month during the TRACER IOP, making multiple (~4) up and down vertical profiles each day that could reach as high as ~1 km. TRACER-Tethersonde included an En-Sci electrochemical cell (ECC) ozonesonde on the TBS. The ozonesonde was connected to an iMet-4RSB radiosonde, and the overall data collected included ozone, relative humidity, temperature, and altitude.
