attribute NC_GLOBAL abstract String Water body chlorophyll-a - Seasonal Climatology for Po River for the period 1960-2020 on the domain: Lon E12.0-14.0deg., Lat N44.0-46.0deg.\nData Sources: observational data from SeaDataNet/EMODNet Chemistry Data Network.\nDescription of DIVA analysis: The computation was done with the DIVAnd (Data-Interpolating Variational Analysis in n dimensions), version 2.7.9, using GEBCO 30sec topography for the spatial connectivity of water masses.\nThe horizontal resolution of the produced DIVAnd maps grids is dx=dy=0.009 degrees (around 975m and 708m accordingly).\nThe vertical resolution is 14 depth levels: [0., 2., 4., 6., 8., 10., 15., 20., 25., 30., 40., 50., 60., 70.].\nA relative correlation length used based on topography gradients and the horizontal correlation length varies from 25 km to 12.5 km. The vertical correlation length (in meters) is:  [4.,4.,4.,4.,4.,10.,10.,10.,10.,20.,20.,20.,20.,20.]. \nDuplicates check was performed using the following criteria for space and time: dlon=0.01deg., dlat=0.01deg., ddepth=0.01m, dtime=1min, dvalue=0.01.\nThe error variance (epsilon2) was set equal to 1. Data weight was reduced at shallow waters. Data weighting was applied with the following threshold values: lon=0.03, lat=0.03, depth=2.\nAn anamorphosis transformation was applied to the data (function DIVAnd.Anam.loglin) to avoid unrealistic negative values: threshold value=200.\nThe mean value was used as background analysis field.\nQuality control of the observations was applied using the interpolated field (QCMETHOD=3). Residuals (differences between the observations and the analysis (interpolated linearly to the location of the observations) were calculated. Observations with residuals outside the minimum and maximum values of the 99% quantile were discarded from the analysis. \nSeasons definition: Winter=Jan-Mar, Spring=Apr-Jun, Summer=Jul-Sep, Autumn=Oct-Dec.\nOriginators of Italian data sets-List of contributors:\n- Brunetti Fabio (OGS)\n- Cardin Vanessa, Bensi Manuel doi:10.6092/36728450-4296-4e6a-967d-d5b6da55f306\n- Cardin Vanessa, Bensi Manuel, Ursella Laura, Siena Giuseppe doi:10.6092/f8e6d18e-f877-4aa5-a983-a03b06ccb987\n- Cataletto Bruno (OGS)\n- Cinzia Comici Cinzia (OGS)\n- Civitarese Giuseppe (OGS)\n- DeVittor Cinzia (OGS)\n- Giani Michele (OGS)\n- Kovacevic Vedrana (OGS)\n- Mosetti Renzo (OGS)\n- Solidoro C.,Beran A.,Cataletto B.,Celussi M.,Cibic T.,Comici C.,Del Negro P.,De Vittor C.,Minocci M.,Monti M.,Fabbro C.,Falconi C.,Franzo A.,Libralato S.,Lipizer M.,Negussanti J.S.,Russel H.,Valli G., doi:10.6092/e5518899-b914-43b0-8139-023718aa63f5\n- Celio Massimo (ARPA FVG)\n- Malaguti Antonella (ENEA)\n- Fonda Umani Serena (UNITS)\n- Bignami Francesco (ISAC/CNR)\n- Boldrini Alfredo (ISMAR/CNR)\n- Marini Mauro (ISMAR/CNR)\n- Miserocchi Stefano (ISMAR/CNR)\n- Zaccone Renata (IAMC/CNR)\n- Lavezza, R., Dubroca, L.
