The phenological information in the Annual Bulletin of Climate Information of the Meteorological Service of Catalonia

The Meteorological Service of Catalonia (SMC) publishes regularly the Annual Bulletin of Climate Indicators with the aim to communicate the state of the climate in Catalonia based on the climate series, the series of sea temperature and sea level, and the phenological series, all of them managed by this institution.The Annual Bulletin of Climate Indicators (known by the acronym 'BAIC' according to its name in Catalan) has eight chapters: air temperature (data from 27 climate series), precipitation (data from 72 climate series), extreme climate indices (based on Expert Team on Climate Change Detection and Indices standards), synoptic patterns (surface and 500 hPa), phenology (information from the Phenological Network of Catalonia), insolation (data from 8 series), secular observatories (information from specific observatories in Catalonia with more than 100 years of daily data) and sea (one series of sea temperature at different depths, mean sea level and sea storms), apart from the introduction, the executive summary (key points of the bulletin) and the references.The SMC created the Phenological Network of Catalonia (Fenocat) in 2013, a citizen science network where 79 observers monitor 25 plant species, 14 bird species and 6 butterflies. 37 of these observers have registered information from the very beginning of the Fenocat, and the results shown are based mostly on their information.The phenology chapter of the Annual Bulletin of Climate Information describes the state of the phenological network, explains the most characteristic features of the phenological situation during the last year and shows the evolution of the onset of the main phenophases from 2013 to the present, as well as the intra-annual variability. Tables are also provided with the value of the trend and its statistical significance.The main results of the latest BAIC will be shown, providing examples of graphics, charts and tables used to convey these results to the society, with the main goal of reporting the state of the climate to the society in the clearest and most rigorous way possible.
