资源简介:
These data are the Goddard Satellite-based Surface Turbulent Fluxes Version-3 (GSSTF3) Dataset recently produced through a MEaSUREs funded project led by Dr. Chung-Lin Shie (UMBC/GEST, NASA/GSFC), converted to HDF-EOS5 format. The stewardship of this HDF-EOS5 dataset is part of the MEaSUREs project. This suite of GSSTF version 3 products is the 0.25x0.25 deg resolution version of the GSSTF 2c collections. It does not contain, however, the "WB" variable - 'lowest 500-m precipitable water' (g/cm**2). This is the Daily (24-hour) product; data are projected to equidistant Grid that covers the globe at 0.25 degree cell size, resulting in data arrays of 1440x720 size. As in previous versions, the daily fluxes have first been produced for each individual available SSM/I satellite tapes (e.g., F08, F10, F11, F13, F14 and F15). Then, the Combined daily fluxes are produced by averaging (equally weighted) over available flux data/files from various satellites. These Combined daily flux data are considered as the "final" GSSTF, Version 3, and are stored in this HDF-EOS5 collection. There are only one set of GSSTF, Version 3, Combined data, "Set1" The "individual" daily flux data files, produced for each individual satellite, are also available in HDF-EOS5, although from different collections: GSSTF_Fxx_3, where Fxx are the individual satellites (F08, F10, etc..) The input data sets used for this recent GSSTF production include the upgraded and improved datasets such as the Special Sensor Microwave Imager (SSM/I) Version-6 (V6) product of brightness temperature [Tb], total precipitable water [W], and wind speed [U] produced by the Wentz of Remote Sensing Systems (RSS), as well as the NCEP/DOE Reanalysis-2 (R2) product of sea skin temperature [SKT], 2-meter air temperature [Tair], and sea level pressure [SLP]. Relevant to this MEaSUREs project, these are converted to HDF-EOS5, and are stored in the GSSTF_NCEP_3 collection. Please use these products with care and proper citations, i.e., properly indicating your applications with, e.g., "using the combined 2001 data file of Set1" or "using the 2001 F13 data file". APPENDIX SET1 --------------- The following list summarizes individual satellites used to produce the Combined SET1.

The Combined daily files will be updated for those three years once an improved set of Individual daily data files are produced using corrected and updated SSM/I F15 input files. (b) The current Combined daily data files are produced with at most 4 combined satellites, i.e., F10, F11, F13 and F14 for May-Nov 1997, and F11, F13, F14 and F15 for Jan-May 2000.

本数据集为美国宇航局戈达德航天中心(NASA/GSFC)郭中麟博士(UMBC/GEST)领导,由MEaSUREs项目资助的最新研究成果——基于戈达德卫星的表面湍流通量数据集版本3(GSSTF3)。该数据集已转换为HDF-EOS5格式,并成为MEaSUREs项目的一部分。该系列GSSTF版本3产品为GSSTF 2c集合的0.25x0.25度分辨率版本,然而,其中不包含“WB”变量——即最低500米可降水量(g/cm²)。该数据集为每日(24小时)产品,数据投影至等距网格,网格覆盖全球,单元格大小为0.25度,形成1440x720大小的数据阵列。与先前版本相同,每日通量首先为每个可用的特殊传感器微波成像仪(SSM/I)磁带(例如,F08、F10、F11、F13、F14和F15)生成。然后,通过平均(等权重)来自不同卫星的可用通量数据/文件生成综合每日通量。这些综合每日通量数据被视为“最终”的GSSTF,版本3,并存储在本HDF-EOS5集合中。存在仅一套GSSTF,版本3,综合数据,即“Set1”。为每个单独卫星生成的“单独”每日通量数据文件也以HDF-EOS5格式提供,尽管来自不同的集合:GSSTF_Fxx_3,其中Fxx为单个卫星(F08、F10等)。用于此最新GSSTF生成的输入数据集包括改进的升级版数据集,如由遥感系统公司(RSS)生产的特殊传感器微波成像仪(SSM/I)版本6(V6)亮度温度[Tb]、总可降水量[W]和风速[U]产品,以及NCEP/DOE再分析2(R2)产品海面温度[SKT]、2米空气温度[Tair]和海平面气压[SLP]。与MEaSUREs项目相关,这些数据已转换为HDF-EOS5格式,并存储在GSSTF_NCEP_3集合中。请谨慎使用这些产品,并适当引用,即正确表明您的应用,例如,“使用Set1的2001年综合数据文件”或“使用2001年F13数据文件”。附录SET1----------------以下是用于生成综合SET1的个别卫星列表。(1) Y1987/:F08/1987/07-12:F08(注意:1987/12因数据稀缺而填充为缺失值)(2) Y1988/:F08/1988/01-12:F08(3) Y1989/:F08/1989/01-12:F08(4) Y1990:F08/F10/1990/01-12:F08(注意:F10从1990/12开始,但因数据稀缺而不适用)(5) Y1991/:F08/F10/1991/01-12:F08+F10(6) Y1992/:F10/F11/1992/01-12:F10+F11(7) Y1993/:F10/F11/1993/01-12:F10+F11(8) Y1994/:F10/F11/1994/01-12:F10+F11(9) Y1995/:F10/F11/F13/1995/01-12:01-04:F10+F11,05-12:F10+F11+F13(10) Y1996/:F10/F11/F13/1996/01-12:F10+F11+F13(11) Y1997/:F10/F11/F13/F14/1997/01-12:01-04:F10+F11+F13,05/01-11/14:F10+F11+F13+F14,11/15-12/31:F11+F13+F14(12) Y1998/:F11/F13/F14/1998/01-12:F11+F13+F14(13) Y1999/:F11/F13/F14/1999/01-12:F11+F13+F14(14) Y2000/:F11/F13/F14/F15/2000/01-12:01/01-05/16:F11+F13+F14+F15,05/17-12/31:F13+F14+F15(15) Y2001/:F13/F14/F15/2001/01-12:F13+F14+F15(16) Y2002/:F13/F14/F15/2002/01-12:F13+F14+F15(17) Y2003/:F13/F14/F15/2003/01-12:F13+F14+F15(18) Y2004/:F13/F14/F15/2004/01-12:F13+F14+F15(19) Y2005/:F13/F14/F15/2005/01-12:F13+F14+F15(20) Y2006/:F13/F14/2006/01-12:F13+F14(21) Y2007/:F13/F14/2007/01-12:F13+F14(22) Y2008/:F13/F14/F15/2008/01-12:01-07:F13+F14,08-12:F13特别说明:(a) 对于Y2006、Y2007和Y2008,由于F15的校准问题,当前的综合每日数据文件不包括F15的单独每日数据文件。一旦使用更正和更新的SSM/I F15输入文件生成了改进的单独每日数据文件,将更新这三年的综合每日文件。(b) 当前的综合每日数据文件使用最多4个综合卫星,即1997年5月至11月的F10、F11、F13和F14,以及2000年1月至5月的F11、F13、F14和F15。
