R/V Ramon Margalef was built in 2012 for oceanographic research purposes. It mainly operates around the Iberian Peninsula and Canary island waters. Since the beginning of its operations, an automatic weather station has been continuously collecting marine meteorological data every minute, both at open sea and in port. The collected data are sent directly to the Spanish Institute of Oceanography (IEO) Data Center / National Oceanographic Data Center for delayed mode quality control and long-term archive. Recently, a semi-automatic process has been used to perform quality control and assessment of the data. Controlled data are stored in a standard MEDAR/MEDATLAS format, and the corresponding quality flag has been added to each individual measurement. This facilitate their reusing for different purposes, from climatology or academical studies to industrial sector needs, between others. In 2023, atmospheric pressure, air temperature, relative humidity, wind speed and direction and solar radiation were collected.
