1. summary: Dai & Trenberth Interannual monthly river discharge, 1948-2007. 2. created by: Steve Yeager 3. date and time: Oct 2010 4. platform: mirage.ucar.edu 5. dataset format: netcdf 6. endian: N/A 7. archival copy location: 8. creation details: Aiguo Dai provided the following raw dataset which contained monthly discharge values from 1948-2006: monthly-dis-Oct1947-Dec2006-2d-scaled-con.bin The data was converted to a flux in kg/s/m^2, filled in to extend to Dec 2007, and written to netcdf with fields required by the dlnd7. The climatological fill used for 2007 was the same as that used by Dai for missing rivers after Oct 2004: 5-year climatology from 10/1999-9/2004. Time-invariant runoff was added for Antarctica based on Large's value of 73000000.0 kg/s (=0.073Sv) for this continent. 9. derived from: /cgd/oce/yeager/OBS/river_runoff/ monthly-dis-Oct1947-Dec2006-2d-scaled-con.bin (obtained by personal communication with A. Dai) 10. code, scripts, namelists, etc, used to create this file: /fs/cgd/home0/yeager/ccsm_forcing/RUNOFF/DaiTren/step1_convert_daitrenrr_2cdf.Oct2010.run /fs/cgd/home0/yeager/ccsm_forcing/RUNOFF/DaiTren/create_dlndstream_daitren.Oct2010.run 11. Notes To check this data file, I ran /fs/cgd/home0/yeager/ccsm_forcing/RUNOFF/DaiTren/check_dlnd7streams.ncl which produced the following output (note: original data did not include antarctic runoff): (0) 1948, global= 1.25064 Sv, ant= 0.073 Sv, amz = 0.222999 (0) 1949, global= 1.28261 Sv, ant= 0.073 Sv, amz = 0.235515 (0) 1950, global= 1.25254 Sv, ant= 0.073 Sv, amz = 0.219741 (0) 1951, global= 1.23044 Sv, ant= 0.073 Sv, amz = 0.220364 (0) 1952, global= 1.23906 Sv, ant= 0.073 Sv, amz = 0.220755 (0) 1953, global= 1.22088 Sv, ant= 0.073 Sv, amz = 0.237915 (0) 1954, global= 1.26562 Sv, ant= 0.073 Sv, amz = 0.227424 (0) 1955, global= 1.22667 Sv, ant= 0.073 Sv, amz = 0.214992 (0) 1956, global= 1.27012 Sv, ant= 0.073 Sv, amz = 0.227147 (0) 1957, global= 1.21186 Sv, ant= 0.073 Sv, amz = 0.214526 (0) 1958, global= 1.18554 Sv, ant= 0.073 Sv, amz = 0.209065 (0) 1959, global= 1.20922 Sv, ant= 0.073 Sv, amz = 0.218698 (0) 1960, global= 1.21446 Sv, ant= 0.073 Sv, amz = 0.217298 (0) 1961, global= 1.2296 Sv, ant= 0.073 Sv, amz = 0.21336 (0) 1962, global= 1.22995 Sv, ant= 0.073 Sv, amz = 0.223843 (0) 1963, global= 1.19478 Sv, ant= 0.073 Sv, amz = 0.200429 (0) 1964, global= 1.18103 Sv, ant= 0.073 Sv, amz = 0.203917 (0) 1965, global= 1.1679 Sv, ant= 0.073 Sv, amz = 0.201768 (0) 1966, global= 1.21685 Sv, ant= 0.073 Sv, amz = 0.19816 (0) 1967, global= 1.2073 Sv, ant= 0.073 Sv, amz = 0.222186 (0) 1968, global= 1.168 Sv, ant= 0.073 Sv, amz = 0.191609 (0) 1969, global= 1.20501 Sv, ant= 0.073 Sv, amz = 0.18947 (0) 1970, global= 1.23076 Sv, ant= 0.073 Sv, amz = 0.206046 (0) 1971, global= 1.22363 Sv, ant= 0.073 Sv, amz = 0.230898 (0) 1972, global= 1.18934 Sv, ant= 0.073 Sv, amz = 0.228012 (0) 1973, global= 1.25441 Sv, ant= 0.073 Sv, amz = 0.227425 (0) 1974, global= 1.28057 Sv, ant= 0.073 Sv, amz = 0.241799 (0) 1975, global= 1.28353 Sv, ant= 0.073 Sv, amz = 0.242853 (0) 1976, global= 1.21181 Sv, ant= 0.073 Sv, amz = 0.233871 (0) 1977, global= 1.1888 Sv, ant= 0.073 Sv, amz = 0.220674 (0) 1978, global= 1.20929 Sv, ant= 0.073 Sv, amz = 0.224767 (0) 1979, global= 1.23501 Sv, ant= 0.073 Sv, amz = 0.212745 (0) 1980, global= 1.20857 Sv, ant= 0.073 Sv, amz = 0.180824 (0) 1981, global= 1.19821 Sv, ant= 0.073 Sv, amz = 0.191946 (0) 1982, global= 1.22607 Sv, ant= 0.073 Sv, amz = 0.229024 (0) 1983, global= 1.20244 Sv, ant= 0.073 Sv, amz = 0.179994 (0) 1984, global= 1.22817 Sv, ant= 0.073 Sv, amz = 0.219837 (0) 1985, global= 1.20013 Sv, ant= 0.073 Sv, amz = 0.206232 (0) 1986, global= 1.20261 Sv, ant= 0.073 Sv, amz = 0.230113 (0) 1987, global= 1.14923 Sv, ant= 0.073 Sv, amz = 0.208938 (0) 1988, global= 1.18621 Sv, ant= 0.073 Sv, amz = 0.209721 (0) 1989, global= 1.23689 Sv, ant= 0.073 Sv, amz = 0.249321 (0) 1990, global= 1.22081 Sv, ant= 0.073 Sv, amz = 0.211161 (0) 1991, global= 1.19866 Sv, ant= 0.073 Sv, amz = 0.214708 (0) 1992, global= 1.11969 Sv, ant= 0.073 Sv, amz = 0.174231 (0) 1993, global= 1.2196 Sv, ant= 0.073 Sv, amz = 0.226645 (0) 1994, global= 1.25354 Sv, ant= 0.073 Sv, amz = 0.246118 (0) 1995, global= 1.18695 Sv, ant= 0.073 Sv, amz = 0.194003 (0) 1996, global= 1.24889 Sv, ant= 0.073 Sv, amz = 0.225673 (0) 1997, global= 1.19603 Sv, ant= 0.073 Sv, amz = 0.212537 (0) 1998, global= 1.23776 Sv, ant= 0.073 Sv, amz = 0.187319 (0) 1999, global= 1.26759 Sv, ant= 0.073 Sv, amz = 0.232914 (0) 2000, global= 1.2484 Sv, ant= 0.073 Sv, amz = 0.227926 (0) 2001, global= 1.20157 Sv, ant= 0.073 Sv, amz = 0.219559 (0) 2002, global= 1.256 Sv, ant= 0.073 Sv, amz = 0.222583 (0) 2003, global= 1.19077 Sv, ant= 0.073 Sv, amz = 0.213456 (0) 2004, global= 1.21195 Sv, ant= 0.073 Sv, amz = 0.205844 (0) 2005, global= 1.22542 Sv, ant= 0.073 Sv, amz = 0.202479 (0) 2006, global= 1.24038 Sv, ant= 0.073 Sv, amz = 0.227914 (0) 2007, global= 1.22115 Sv, ant= 0.073 Sv, amz = 0.217257
