We are currently working on a regular (~monthly) update of the TropFLux product until 3-4 months behind realtime, which should be available by 2012. 48 Wind stresses and the four components of net surface heat flux are currently 49 available for the entire 1979 to September 2011 period. 50 We are currently working on a regular (~monthly) update of the 51 TropFLux product until 3-4 months behind realtime, which should be 52 available by 2012. 38 53 39 TropFlux is largely derived from a combination of `ERA-I <http://www.ecmwf.int/research/era/do/get/era-interim>`_ re-analysis data for turbulent and longwave fluxes, and `ISCCP <http://isccp.giss.nasa.gov/>`_ surface radiation data for the shortwave flux. All input products are bias- and amplitude-corrected on the basis of `Global Tropical Moored Array <http://www.pmel.noaa.gov/tao/global/global.html>`_ data, before surface net heat flux is computed using the `COARE v3 bulk algorithm <http://www.coaps.fsu.edu/COARE/flux_algor/>`_. 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. (2011) <http://www.locean-ipsl.upmc.fr/~tropflux/papers/TropFlux_paper_accepted_r.pdf>`_. 54 TropFlux is largely derived from a combination of 55 `ERA-I <http://www.ecmwf.int/research/era/do/get/era-interim>`_ 56 re-analysis data for turbulent and longwave fluxes, and 57 `ISCCP <http://isccp.giss.nasa.gov/>`_ 58 surface radiation data for the shortwave flux. 59 All input products are bias- and amplitude-corrected on the basis of 60 `Global Tropical Moored Array <http://www.pmel.noaa.gov/tao/global/global.html>`_ 61 data, before surface net heat flux and wind stresses are computed using the 62 `COARE v3 bulk algorithm <http://www.coaps.fsu.edu/COARE/flux_algor/>`_. 63 A precise description of the flux computation procedure, as well as a 64 detailed evaluation against other timely, daily air-sea heat flux 65 alternatives (OAFLUX, NCEP, NCEP2, ERA-I) is provided in 66 `Praveen Kumar et al. (2011) <http://www.locean-ipsl.upmc.fr/~tropflux/papers/TropFlux_paper_accepted_r.pdf>`_. 67 The wind stress product is described, evaluated and compared against other 68 widely used products (QuickSCTA, NCEP, NCEP2, ERA-I) in 69 `Praveen Kumar et al. (submitted) <http://www.locean-ipsl.upmc.fr/~tropflux/papers/tropflux_stress_submitted_r.pdf>`_ 40 70 41 71 We believe that this product offers the following advantages: 42 72 43 - better variability and less biases than re-analysis fluxes (and equivalent performance to OAFLUX) 44 - available until Septempber 2011, and soon updated every month, lagging realtime by ~3 months 45 - a simple estimate of surface shortwave radiation is provided from OLR data, as a near-realtime alternative to the more accurate but irregularly updated ISCCP data 73 - better variability and less biases than re-analysis fluxes (and equivalent 74 or slightly better than the best performing products: 75 `OAFLUX <http://oaflux.whoi.edu/>`_ for heat fluxes and 76 `ERA-I <http://www.ecmwf.int/research/era/do/get/era-interim>`_ 77 for wind stresses) , 78 - available until Septempber 2011, and soon updated every month, lagging 79 realtime by ~3 months, 80 - a simple estimate of surface shortwave radiation is provided from OLR 81 data, as a near-realtime alternative to the more accurate but irregularly 82 updated ISCCP data. 46 83 47 The TropFLux product has been developed under a collaboration between `Institut Pierre Simon Laplace <http://www.ipsl.fr/>`_, France and `National Institute of Oceanography/CSIR <http://www.nio.org/>`_, India. 84 The TropFLux product has been developed under a collaboration between 85 `Institut Pierre Simon Laplace <http://www.ipsl.fr/>`_, France and 86 `National Institute of Oceanography/CSIR <http://www.nio.org/>`_, India. 48 87
