Using meteorological input data from NCEP
This description is kindly provided by Jooil Kim and Bob Dattore (NCAR).
Now there exists a well-managed source of archived windfields from NCEP for use with FLEXPART. Here are the instructions:
- Go to website: http://dss.ucar.edu/datasets/ds093.0/
- Log in with your ucar account (create one for free if you don't have one yet)
- Go to "Data Access" -> "Internet Download" -> "Request a Subset with Format Conversion". This opens a window for choosing a customized subset of the CFSR data.
- Choose your time period, and select "FLEXPART Model Input - 6-hour Forecasts" under the oarameter presets. When done, press the "Continue" button on the bottom of the page.
- On the next window, look for the "Type of Product" menu and select "all available", then press the "Click Here" button to update. Doing this will give you the analysis (H+0) and H+1 to H+6 forecast fields. When done, push the "Submit Request" button.
- You will receive an e-mail from UCAR when the data is ready. Follow instructions on the e-mail regarding ways to download the data.
- Note: The analysis data (labeled "pgbhnl") do not include all of the surface variables like 2 m temperature and 10 m winds, and so can't be used in FLEXPART. Use the 6 h forecast files (H+6) instead.
