Field contains the mean orientation of the accumulation area of the glacier, centered on cardinal points (N, NW, W, SW, S, SE, E, and NE). This data is facultative. The information related to the '50s time step comes from the Inventory of the Italian glaciers edited by CNR-CGI (1959-1962), while for the other time steps (1988-1989, 2006-2007, 2015) is defined through GIS techniques.

Maximum length of the glacier in kilometers measured along the main flowline in a horizontal projection.

HYD_YEAR refers to the hydrological year during which the glaciological campaigns took place.

In the framework of the National Project of Interest Nextdata, we developed procedures for the automatic flagging and formatting of trace gas, atmospheric aerosol and meteorological data to be submitted to Global Atmosphere Watch programme by the World Meteorological Organization (WMO/GAW). In this work, we describe a first prototype of a centralized system to support Italian atmospheric observatories towards a more efficient and objective data production and subsequent submission to WMO/GAW World Data Centers (WDCs). In particular, the atmospheric variables covered by this work were focused on near-surface trace gases, aerosol properties and (ancillary) meteorological parameters which are under the umbrella of the World Data Center for Greenhouse Gases (WDCGG, see https://ds.data.jma.go.jp/gmd/wdcgg/), World Data Center for Reactive Gases and World Data Center for Aerosol (WDCRG and WDCA, see http://ebas.nilu.no). For different Essential Climate Variables (ECVs), we developed specific routines for data filtering, flagging, format harmonization and creation of data products (i.e. plot of raw and valid-corrected-averaged ECV data and internal instrument parameters) useful for detecting instrumental problems or atmospheric events. A special suite of products based on the temporal aggregation of valid ECV data (like the “calendar” or “timevariation” products) were implemented for quick data dissemination towards stakeholders or citizens. Generated Level-0, Level-1 and Level-2 files are formatted according to NASA-Ames standard. The list of flags adopted is defined in the framework of ACTRIS-2 project (see https://ebas-submit.nilu.no/Submit-Data/Data-Reporting/Templates/Category/). Three different data levels are produces according with WMO/GAW WCDRG and WCDA data reporting guidelines (see also https://ebas-submit.nilu.no/Submit-Data/Data-Reporting): • Level-0: annotated raw data; format instrument specific; contains all parameters provided by the instrument; contains all parameters/info needed for processing to final value; "native" time resolution; • Level-1: data processed to final parameter (calibration and correction implemented to data series), invalid data and calibration episodes removed, "native" time resolution, normalization to standard temperature and pressure (i.e., 273.15 K, 1013.25 hPa) if necessary; • Level-2: data aggregated to hourly averages, atmospheric variability quantified by standard deviation or percentiles. The automatic processing is executed by a set of three“R” scripts specifically designed for each instrument/ECV : • “D20” is the script devoted to the production of Level-0 data files • “D21” is the script devoted to the production of Level-1 and Level-2 data files • “D22” is the script devoted to the generation of data products All the developed scripts are virtually stand-alone and any hypotetical user, after installing an "R" environment, can use them on his/her own PC (both Linux or Windows) or server, for automatic and on-demand application. Of course, some activity of customization is needed by the users to properly set current directory paths, file names, etc etc. A dedicated script containing three R functions has also been implemented for managing numflag creation and aggregation. D20 and D21 scripts have been revised for inconsistencies within the header. Users are recommended to use the version "1907".

Dataset containing available time series of annual and multi-annual mass balance measurements for monitored Italian glaciers.

Since May 2018, a Cavity Ring Down Spectrometer Picarro G2401 is running at the CNR "O. Vittori" Observatory, part of the WMO/GAW global station Mt. Cimone. This instrument is currently under processing to be labelled in the frame of ICOS Research Infrastructure (www.icos-ri.eu). ICOS (Integrated Carbon Observation System) has as its main mission to provide the long-term observations required to understand the present state and predict future behavior of the global carbon cycle and greenhouse gas emissions. ICOS is a distributed research infrastructure comprising three coordinated, complementary operational observation networks: atmospheric observatories of concentrations of CO2, CH4, N2O and other greenhouse gases (GHG’s), terrestrial flux tower sites to measure the ecosystem exchange of CO2, water vapour and energy, and oceanographic observation platforms including volunteer ships monitoring air-sea fluxes. Data will be provided by the ICOS Carbon Portal troughout their web site https://data.icos-cp.eu/portal/#search
