The size distribution (SD) and optical absorption of carbonaceous particulate matter (CPM) was measured online using a Scanning Mobility Particle Sizer (SMPS), a 7λ-aethalometer and an inhouse developed 4λ-Photoacoustic Spectrometer. Based on the SD data, the measurement period could be classified into days with and without new particle formation events (normal days and nucleation days), although particular nucleation-like events were observed on normal days as well. Three characteristic size modes were observed with CMDs of circa 15, 25 and 110 nm that corresponded to the nucleation, traffic and heating modes. Based on the temporal behavior of these modes both types of days were divided into distinctive daily periods (heating hours, traffic hours and nucleation hours). The optical absorption spectra (OAC and AAE) also displayed the same part of day behavior to that of SD. That way this paper is among the first to assess the optical response of urban nucleation events. Due to the simultaneous measurement of OAC by the 7λ-aethalometer and a 4λ-Photoacoustic Spectrometer, OAC was measured overall at 11 wavelengths. That way aethalometer correction factors (f and C) were determined at all aethalometer wavelengths using in situ reference photoacoustic measurements. Correction factors were found to have both wavelength and time of the day variation. In the case of f, no clear trend could be observed, however, Cref values increased both as a function of wavelength.}, year = {2019}, eissn = {1878-7320}, pages = {96-109}, orcid-numbers = {Tóth, Ádám/0000-0001-9928-3212; Hoffer, András/0000-0002-4207-9197; Szabó, Gábor/0000-0001-6756-4677} } @{MTMT:30663582, title = {Légköri nukleáció spektrális válaszának vizsgálata fotoakusztikus módszerrel}, url = {https://m2.mtmt.hu/api/publication/30663582}, author = {Ajtai, Tibor and Kun-Szabó, Fruzsina and Fekete, János and Utry, Noémi and Kiss-Albert, Gergely and Szabó, Gábor and Bozóki, Zoltán}, booktitle = {Kvantumelektronika 2018}, unique-id = {30663582}, year = {2018}, orcid-numbers = {Szabó, Gábor/0000-0001-6756-4677} } @article{MTMT:3328898, title = {Thermo-optical properties of residential coals and combustion aerosols}, url = {https://m2.mtmt.hu/api/publication/3328898}, author = {Pintér, Máté and Ajtai, Tibor and Kiss-Albert, Gergely and Diána, Kiss and Utry, Noémi and Janovszky, Patrick Martin and Palásti, Dávid Jenő and Smausz Kolumbán, Tamás and Kohut, Attila and Hopp, Béla and Galbács, Gábor and Kukovecz, Ákos and Kónya, Zoltán and Szabó, Gábor and Bozóki, Zoltán}, doi = {10.1016/j.atmosenv.2018.01.036}, journal-iso = {ATMOS ENVIRON}, journal = {ATMOSPHERIC ENVIRONMENT}, volume = {178}, unique-id = {3328898}, issn = {1352-2310}, year = {2018}, eissn = {1873-2844}, pages = {118-128}, orcid-numbers = {Pintér, Máté/0000-0003-1905-9603; Smausz Kolumbán, Tamás/0000-0002-5184-6124; Kohut, Attila/0000-0003-4545-2943; Hopp, Béla/0000-0002-4272-7721; Galbács, Gábor/0000-0002-1799-5329; Kukovecz, Ákos/0000-0003-0716-9557; Kónya, Zoltán/0000-0002-9406-8596; Szabó, Gábor/0000-0001-6756-4677} } @misc{MTMT:3328933, title = {Emisszió kontrollált üzemanyagfejlesztés támogatása fotoakusztikus módszerrel}, url = {https://m2.mtmt.hu/api/publication/3328933}, author = {Ajtai, Tibor and Utry, Noémi and Pintér, Máté and Kiss-Albert, Gergely and Szabó, Gábor and Bozóki, Zoltán}, unique-id = {3328933}, year = {2017}, orcid-numbers = {Pintér, Máté/0000-0003-1905-9603; Szabó, Gábor/0000-0001-6756-4677} } @misc{MTMT:3328928, title = {Két-hullámhosszú termodenuderes fotoakusztikus mérőműszer fejlesztése}, url = {https://m2.mtmt.hu/api/publication/3328928}, author = {Kiss-Albert, Gergely and Pintér, Máté and Utry, Noémi and Simon, Károly András and Ajtai, Tibor and Szabó, Gábor and Bozóki, Zoltán}, unique-id = {3328928}, year = {2017}, orcid-numbers = {Pintér, Máté/0000-0003-1905-9603; Szabó, Gábor/0000-0001-6756-4677} } @misc{MTMT:3328917, title = {Aeroszol-mérésre és forrásazonosításra optimalizált két-hullámhosszú fotoakusztikus rendszer}, url = {https://m2.mtmt.hu/api/publication/3328917}, author = {Simon, Károly András and Kiss-Albert, Gergely and Pintér, Máté and Utry, Noémi and Ajtai, Tibor and Szabó, Gábor and Bozóki, Zoltán}, unique-id = {3328917}, year = {2017}, orcid-numbers = {Pintér, Máté/0000-0003-1905-9603; Szabó, Gábor/0000-0001-6756-4677} } @{MTMT:3328914, title = {Légköri aeroszol komplex mikrofizikai és spektrális tulajdonságainak vizsgálata téli városi környezetben}, url = {https://m2.mtmt.hu/api/publication/3328914}, author = {Pintér, Máté and Kiss-Albert, Gergely and Utry, Noémi and Ajtai, Tibor and Szabó, Gábor and Bozóki, Zoltán}, booktitle = {Tavaszi Szél 2017 Konferencia.
