Time to do equipment calibration





After a mild autumn, the real winter has arrived at Lönnstorp Research Station. Over the last two weeks, temperatures have been below zero, with a minimum of -12ºC, according to the automatic weather station. These low temperatures have caused ice to form on the sea surface, which is just 3 km away from the station, and the fields around the station are covered in snow.
Despite the winter conditions, the station staff are already thinking about the spring season, as there is less than two months until the first crops should be sown and therefore time to check and calibrate the spectral equipment.
