Readme file to use wp/rass data in the fortran program First four lines can be skipped which gives information about Date , Month Year and Station One line gives starting hour of observation . This can be read as title1 and print in the program on the top of every calculations Four lines can be skipped which are titles for values. Thirty two lines which are range bins contains the data values i.e rangebin, u, usnr, v, vsnr, w, wsnr ws, wd Rangebin Height in kms U - Zonal Wind in meter/sec USNR - Signal to noise ratio in zonal direction in db V - Meridional Wind in meter/sec VSNR - Signal to noise ratio in meridional direction in db W - vertical Wind in meter/sec WSNR - Signal to noise ratio in vertical direction in db WS - Scalar wind speed in meter/sec WD - Wind direction in degrees U,V,W - According to Meteorological convention. Negative W velocity includes fall velocity. -99.99 - Data not available. Format to read Format (4x,f5.2,8(5x,f6.2)) How to read in fortran program Do 1 i=1,4 1 read(unit,’(a)’)title do 2 j=1,hour do 3 i=1,1 3 read (unit,’(a)’)title1 do 4 i=1,4 4 read(unit,’(a)’)title do 5 i=1,32 read(unit,‘(4x,f5.2,8(5x,f6.2))’)range(i),u(i),usnr(i),v(i),vsnr(i),w(i),wsnr(i),ws(i),wd(i) 5 continue do 6 i=1,2 6 read(unit,’(a)’)title 2 continue This will skip four lines then put value of hour (no. of hours available) Read starting hour from title1 which can be printed before results so that it can be identified by hour Then again four lines to be skipped as a titles Then read all data i.e 32 rangebins available Then again skip two line as a title.
