1. Here is the file format we need for the submitted simulations. Recall that we have requested hourly time series of simulated instantaneous discharge in Z time. The FORTRAN (in one case C/C++) statements that will generate this format are provided below. The data files consist of 2 sections: Header with comment lines and two lines of descriptive data, and the data values themselves. a. Header Format Header information is necessary for identifying and managing the files. - Comment lines: text lines (each line not more than 80 characters) that include participants name and other information a participant wants to note, such as model name, time step, type of simulation, etc. Comment lines start with an '$' sign in the first position; - First Non-Comment Header line: write(*,20) dtype,dimens,units,dt,id 20 format(14X,A5,A5,A5,A5,A15) where: dtype= 'SQIN '; dimens= 'L3/T '; units= 'CMS '; dt= '1 '; id= - Second Non-Comment Header line: write(*,30) strt_month,strt_year,end_month, end_year,ncol,format 30 FORMAT(I2,2X,I4,X,I2,3X,I4,X,I2,3X,A5) where: strt_month & strt_year are starting month and year of simulations, (MM YYYY) end_month & end_year are ending month and year of simulations, (MM YYYY) ncol=' 1'; format='F10.3' Recall in the DMIP Modeling Instructions that the beginning of the calibration period is May 1, 1993 and the end of the calibration period is May 31, 1999. The beginning of the validation period is June 1, 1999, and the end is July 31, 2000. However, there is only input NEXRAD data for part of May, 1993. Participants can start their model runs whenever they want, but must submit simulated time series starting on June 1, 1993. For convenience, participants should submit simulations (calibrated and uncalibrated) for the entire period of June 1, 1993 to July 31, 2000. HL has software that can separate the calibration period and validation period to compute statistics. HL's software can also compute statistics on individual events as well as the entire run period. b. Data Format Two format statements are provided for actually writing the discharge data values to the file: one in FORTRAN, the other in C/C++. a) FORTRAN WRITE(*,10) five_letter_basin_id, day, month, year, hour, discharge 10 FORMAT(A5,5x, 3I2, I4, F9.3) b) C or C++ fprintf("%s %02d%02d%02d%4d%9.3f\n", five_letter_basin_id, day,month,year,hour,discharge); 2. NOTES: a. discharge values must be in CMS (cubic meters per second) b. the format specification of the data must begin in column 21. c. Complete months of data must be present. For example, the first value in the time series must be for the first hour of the first day of the month (e.g., June 1, 1993 at 1 Z). The last value in the time series must be for the last hour of the last day of the last month, (e.g., July 31, 2000 at 24Z). In order to satisfy this requirement, submitted time series should start on June 1, 1993 and end on July 31, 2000. 3.
