Weather Station

Attention:

The facilities of the meteorological observatory can be co-used by scientists for special measurements. The observatory is always manned with a weather radio technician and a meteorologist during scientific cruises.

Summary

Responsible Persons

Components

The weatherstation consists of different sensors (subdevices) and a data acquisition unit. The data acquisition unit developed by FIELAX provides local data storage and data transfer to the DShip system. In addition,
it facilitates the receipt of weather information and satellite images. The German Weather Service (DWD) provides the required forecast producst via e-mail.

Subdevices

Position

Data logging, storage and archiving

Logged parameters

Central geographical ship's position and time standard

Time synchronising is regulated via ntp between the acquisition computer xdas1 and the central ntp-server on board.

??? The geographical ship's position is transferred to ???
??? centering of the GPS Position to ???

Rawdata storage on board

All raw data are stored to the DShip System.

Dship

All raw data are stored to the DShip System:

Device name	weatherstation
Parameters	air pressure [hPa]; air temperature [°C]; ceiling [ft]; dewpoint rows nest [°C]; direct radiation [W/m2]; global radiation [W/m2]; max rel. wind velocity last min [m/s]; precipitation [mm/min]; rel. humidity [%]; rel. wind direction [deg]; rel. wind velocity [m/s]; sunshine indicator; true wind direction [deg]; true wind velocity [m/s]; visibility [m]; water temperature [°C]

Data archiving on land

The acquired data are evaluated, archived and made available via Internet by the AWI.
DShip data set can be extracted from https://dms.awi.de.
