4 Time period	July, August 1999
5 Location:	Cape Hedo temporal observatory, Okinawa Island, Japan (26o52'N, 128o15'E, 90m asl)
6 List of observed (output) species	HOx (OH+HO2), OH (with low S/N ratios), CO, hydrocarbons, O3, RH, T, P, NO, NO2, J(NO2), HCl, HNO3, SO2, HCOOH, HCHO, CH3CHO, H2O2, DMS, COS, trace metals/aerosol (Al, Ti, V, Mn, Fe, Ni, Zn, As, Se, Sb), aerosol size distribution (OPC)
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; wind data are based on 10 min; instantaneous sampling for NMHCs, aerosols (24-hour or 4-hour sampling for intensive period) Metal data are based on 24-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 Cape Hedo, Okinawa Island, a subtropical remote island in the southwest part of Japan, in July-August 1999, to explore radical photochemistry in the remote atmosphere. University of Tokyo, Keio University, and Osaka Prefectural University took part in the campaign.
