    9 Simple description of the data In September of 2003 we conducted an intensive field campaign at Rishiri Island, with a focus on studying OH and HO2 chemistry under daytime coastal conditions and nighttime forest-like conditions. Both of the conditions were expected from changes in the air mass over the site associated with land-sea breezes. In this campaign, precise measurements were made of the concentrations of OH and HO2 radicals using an improved LIF instrument, accompanied by simultaneous measurements of a full suite of chemical species and parameters. Continuous measurements of total monoterpene concentrations were performed via proton-transfer reaction-mass spectrometry (PTR-MS) to provide an improved analysis of nighttime chemistry. NIES, FRCGC/JAMSTEC, Hokkaido Univ., Keio Univ., RCAST/Univ. Tokyo, Tokyo Metropolitan Univ. participated.
