An online tool that helps you to generate your own hourly surface meteorological data files, which can be used to run AERMET.
This tool converts hourly surface meteorological data which is contained in an Excel file to the SAMSON file format. Use of SAMSON file format is quite common among AERMOD users, because, AERMET can extract hourly surface weather observations from SAMSON file. AERMET can not extract meteoroglogical data from Excel file. AERMET is preprocessor for organizing available meteorological data into a format suitable for use by the AERMOD air dispersion model.
SAMSON (Solar And Meteorological Surface Observation Network) is one of the several standard format used storage and distribution meteorological data.
AERMET is preprocessor for organizing available meteorological data into a format suitable for use by the AERMOD air dispersion model.
File Preparation
The excel file must have the Parameter Identifier in the first row of the respective data column. The highlighted parameters are mandatory.
| YY | Year | YYYY (as 2022) |
|---|---|---|
| MM | Month | MM (as 01-12) |
| DD | Date | DD (as 01-31) |
| HH | Hour | HH (as 00-23) |
| WS | Wind Speed | m/s |
| WD | Wind Direction | from Noth |
| AT | Ambient Temperature | oC |
| RH | Relative Humidity | % |
| RF | Rainfall | mm |
| CC | Cloud Cover | tenth |
| DP | Dewpoint | oC |
| SP | Station Pressure | mb |
| CH | Ceiling Height | m |
| GR | New Global Radiation | wh/m2 |
For now this application does not convert units therefore, the unit of the data in the file must be as indicated in the table.
Use negative (-) sign with degree (latitude/longitude) to indicate WEST or SOUTH
The application may estimate Global Radiation if the primary parameteres are availble. To enable this option tick the check box "Estimate Missing Data".
