Thermo 49i

Misure continuative di ozono superficiale sono eseguite presso l'Osservatorio Climatico – Ambientale di Capo Granitola attraverso un analizzatore ad assorbimento UV Thermo 49i. La risoluzione temporale dei dati grezzi e' pari ad 1 minuto. Ogni 24 ore vengono eseguiti in modo automatico controlli di zero e span utilizzando una sorgente esterna di aria pulita ed un generatore interno di ozono. Nell’ambito del network I-AMICA esso sarà tarato attraverso un calibratore secondario riferito alla scala internazionale GAW-WMO.

Instrument (Thermo 49i) is connected by a Teflon pipe (OD: ¼”) to the air intake manifold. Antiparticulate filter (Teflon material) are present at the instrument inlet (changed every 30 days).

Internal span source (ozonator) and external zero source (Purafill© filled cartridge) allow the daily execution of zero/span check.

Instrument will be calibrated in-situ on a yearly basis against a travelling calibrator (thermos 49iPS) hosted at the “twin” I-AMICA station of Lecce. The travelling calibrator will be compared against the standard reference SRP15 hosted at the GAW WCC at EMPA.

Data are recorded on a 1-minute basis by a station server and delivered in NRT mode to ISAC-CNR HQs in Bologna.

Information about instrument functioning and intervention are stored within an e-logbook. Instrument manual are present at the station.

SOP are extracted by the GAW Report No. 209 “Guidelines for Continuous Measurements of Ozone in the Troposphere”
