How to create your own time series for use on the PSL composites web pageChange: The ability to use your own http address for custom files is no longer supported due to security restrictions.
You can use your own monthly value timeseries in the composites web page. The file format is as follows (the old format with no years in the first line will no longer work).
iyearstart xm1 xm2 xm3 xm4 xm5 xm6 xm7 xm8 xm9 xm10 xm11 xm12
iyearend xm1 xm2 xm3 xm4 xm5 xm6 xm7 xm8 xm9 xm10 xm11 xm12
The first row contains the starting and ending years. The starting year should be 1948 or after. The ending year can be anything up through the current year. The next set of rows is yearstart through yearend in which the first column of each row contains an integer year and the next 12 columns contain the 12 monthly values for that year. They should be separated by spaces! You must have a missing value at the end of the file followed by a return (even if there is no missing data). You also must have lines for all the years. Choose a missing value not in the range of your timeseries. Using 0 is generally not a good idea. If you don't have 12 monthly values, you can "fool" the code by putting the value for the month you do have and fake values for the rest. If you have seasonal values, put the same value in for each month of the season. You can even fool the code further by leading or lagging your time series. Be sure you have values for all columns and rows even if you don't plan on using them.
The time series can be used by specifying the FULL path in the box after "custom" (you must check custom). You must use a full (not relative) pathname.
