r185 r186 8 8 ----------------------------- 9 9 10 The TropFlux project aims at providing daily, timely, accurate air-sea heat and momentum flux data for the entire 30°N-30°S region. Wind stresses and the four components of net surface heat flux are currently available for the entire 1979 to eptember 2011 period. We are currently working on a regular (~monthly) update of the TropFlux product until 3-4 months behind realtime, which should be available in 2012.10 The TropFlux project aims at providing daily, timely, accurate air-sea heat and momentum flux data for the entire 30°N-30°S region. Wind stresses and the four components of net surface heat flux are currently available for the entire 1979 to september 2011 period. We are currently working on a regular (~monthly) update of the TropFlux product until 3-4 months behind realtime, which should be available in 2012. 11 11 12 TropFlux is largely derived from a combination of ERA-I re-analysis data for turbulent and longwave fluxes, and ISCCP surface radiation data for shortwave flux. All input products are bias- and amplitude-corrected on the basis of Global Tropical Moored Buoy Array data, before surface net heat flux and wind stresses are computed using the COARE v3 bulk algorithm. A precise description of the flux computation procedure, as well as a detailed evaluation against other timely, daily air-sea heat flux alternatives (OAFLUX, NCEP, NCEP2, ERA-I) is provided in Praveen Kumar et al. 201 1. The wind stress product is described, evaluated and compared against other widely used products (QuikSCAT, NCEP, NCEP2, ERA-I) in Praveen Kumar et al. submitted12 TropFlux is largely derived from a combination of ERA-I re-analysis data for turbulent and longwave fluxes, and ISCCP surface radiation data for shortwave flux.
