2 Acronym: risotto
3 date March 2008 (final data)
4 Time period June, 2000
5 Location: Rishiri observatory (45.07N, 141.12E, 35 m asl), Hokkaido, Japan
6 List of observed (output) species HOx (OH+HO2), OH (with low S/N ratios), CO, wind, T, RH, precipitation, O3, NO, NO2, HNO3, NMHC, PANs, HCHO, CH3CHO, J values (JNO2, JO1D, JHCHOrad, JHCHOmol, JCl2, JHOCl, JBr2, JHOBr, JH2O2), Cl-, NO3-, SO4 2-, NH4+, K+, Ca2+, Mg2+
7 Time resolution, averaging time, time stamp basically 1 hour. Exceptions: 1-min for raw OH and HO2 data and NO/NO2, and JNO2 data; instantaneous sampling for NMHCs, aerosols (4-hour sampling); The time stamp corresponds to the beginning of the average time period.

    9 Simple description of the data We conducted an intensive field campaign at Rishiri Island, located in the north part of Japan, in June 2000 (following half-year measurements of NOx/PANs/HNO3), to explore radical photochemistry in the remote atmosphere. University of Tokyo and Keio University took part in the campaign.
