These data were developed at CICS/ESSIC. This file briefly describes the analysis and tells how to read the data. Questions or comments about the data should be addressed to Tom.Smith@noaa.gov. Constructive feedback about the analysis, its uses and limitations, and suggestions for improvements are also welcome. Data: historical reconstructed precipitation anomalies. These are inputs to the merged analysis. The EOF-based analysis is monthly and called recg.blend.ascii.dat. The CCA-based analysis is annual and called rcca.ascii.dat. They are both read the same way as the merged data file, except that for the CCA-based analysis there is only one read per year. Grid: 5-deg latitude by longitude. The 72 longitudes are centered on 2.5E (i=1) to 357.5E (i=72). The 36 latitudes are centered on 87.5S (j=1) to 87.5N (j=36). The polar latitudes are not analyzed and are filled with special values (-99999) to mark them. Data are written as integers. To extract the data and convert the values to mm/mon, use the following code: c 67 1 2 3 4 5 6 7 2 parameter(im=72,jm=36,iyr1=1900,iyr2=2008) real a2(im,jm) integer ia2(jm) c c* Open the input data file. open(21,file='recg.bias.adj.blend.ascii.dat') c c* Convert the real numbers to ascii text to real numbers (mm/mon). do iy=iyr1,iyr2 c c* For readint the CCA-based analysis, there is only 1 read/year c* and this loop over months is not used. c do mon=1,12 c c* Read in the year and month for each month in the record. read(21,90) iyr,monr c* Read in the data as ascii mm/mon x 100 and convert to real mm/mon. c* Regions with no data at high latitudes are marked -99999 in ascii, c* and converted to -999.99 in real numbers. do i=1,im read(21,91) (ia2(j),j=1,jm) do j=1,jm a2(i,j)=real(ia2(j))/100.0 end do end do c* Data are now in array a2(i,j). c* End loop over months for the EOF-based analysis. end do c c* End loop over years. end do c stop 90 format(2i7) 91 format(36i7) end
