AZMET offers two types of comma delimited (ASCII format) data files: Hourly and Daily.
These raw data files can be loaded into spreadsheets and databases such as Excel and Access, etc. The raw files can also be read by advanced programming languages. In all raw data files, the units of measurement are Metric. In 1999 we changed the depths of our soil temperature sensors : 1999 Soil Temperature Depths |

AZMET weather stations record and store data in metric units. The data contained in our Raw Hourly and Daily files is in metric units. The word 'English' here does not refer to the language. 'English' units are those units of measurements which were standardized and used throughout Great Britain. |
