Lettau Automatic Weather Station, 2017 quality-controlled observational data.

Listed in AMRDC Data Repository

These files contain monthly observational data that have been quality-controlled using semi-automated computer programs as well as oversight by our staff.

Description

The filenames are prefixed with a label identifying one of three different observation intervals - ten minute (10min), one hour (1hr), and three hour (3hr). The rest of the filename consists of a standardized string composed of (in order) a three-letter code to indicate the station, the year, the month, and the frequency of the data (e.g. 3hr-[III][YYYY][MM]q3h.txt for three-hourly data).

Each set of daily observations begins at 0000 UTC. The hourly data are recorded at the top of every hourly interval: i.e. at 0000 UTC, 0100 UTC, 0200 UTC, 0300 UTC, etc. for the one-hour data; and at 0000 UTC, 0300 UTC, 0600, etc. for the three-hour data. Missing data are represented as 444.0.
