HELP IN CREATING WEATHER FILES IN ARCSWAT 2009

[emeka....@unn.edu.ng]

I am working on ArcSWAT 2009 (ArcGis 9.3). Please i need your help in creating weather input file for my study area. I collected weather data from a weather station in excel format. I have already ran the DEM, LAND & SOIL SIMULATION and next is the weather
In the EDIT SWAT INPUT option, i clicked on DATABASES which opened to the USER WEATHER STATIONS. I added and created my WEATHER STATIONS. When i clicked the Weather stations under the Write input Tables, i clicked on the custom Databases. I did not see the weather stations i created under the user weather stations.
Please, i have read through the documentation, but i did not see how to create user weather files except the one found in the example folder i used in practicing. Please help me in creating a user weather file for my study area.
Please i need help from SWAT Users

I think that when SWAT asks about the weather-station database, it is looking for stations for which you have all the necessary statistical parameters, so that it can generate missing weather values as needed.  If you're not working in the USA, you'd need to calculate these statistics based on weather stations in your area -- see the WGEN program (I think it's called that) on the SWAT webpage.  I haven't done this myself, so I'm partially guessing here. 

The files giving names and locations of specific stations for which you have precipitation and temperature are entered under dialog boxes for those variables.

I think Jim may be referring to WGN Excel Macro which is on this page -   http://swat.tamu.edu/software/links-to-related-software/  We have just recently run this and it seems to have done what was needed with our weather station data.  We used Excel 2007 - .xlsx files as input, but I believe you can use .xls or .txt files.  There is a decent manual that comes with it.
