Hilo Ozone Climatologies Monday, January 17, 2022

Ivanka’s Recommendations for averaging and LBCs • Remove ozone concentrations less 10 ppb • Possible volcano emission influences • Check for missing measurement levels in program • Hilo, HI ozonesonde spacing typically every 250 m • Missing levels in profiles • Also removed one corrupted October 1987 ozonesonde • Recommended testing Hilo as Lateral Boundary conditions for CMAQ Hawaii Domain

Hawaii Domains Hysplit CMAQ WRF-ARW

Hawaii Verification CONUS static BC runs Marina Tsidulko, Jianping Huang, Youhua Tang

Averaged Ozone(ppb) w/ height for all Months to 14 km 1982 -2007, Hilo, HI Near sfc • Highest : March-Apr • Lowest: July-Sep Above 10 km: • Highest: April-June • Lowest: July-Sep

Averaged Ozone (ppb) w/ height for all Months to 3 km 1982 -2007, Hilo, HI Near sfc • Highest : March-April • Lowest: July-Sep • Monthly Variability as much as 10 ppb near surface. • Should be accounted for in CMAQ Hawaii runs

Codes/Scripts • Profileavg. f – On cirrus at /meso/wx 22 mc/jeff/gempak/profplot – Usage: profileavg [ozonesonde file name] • Program will also ask for month to average – Ozonesonde file includes all sondes from 1982 -2007 • Located at osonde/hilo 2. lvl – Output file: gemin. dat • Plotted using gempak/nawips: snedit & snprof • Or run mk-multplot. sh
