The data set includes the noise contours which have been reported by countries under the terms of the Environmental Noise Directive (END) by EEA member countries for the 2022 round of strategic noise mapping. The data set includes submissions from the countries until 18/11/2024. Under the terms of the END, countries have to produce noise contour maps for major sources of noise (i.e. major roads with more than 3 000 000 vehicle passages a year, major railways with more than 30 000 train passages per year and airports with more than 50 000 movements per year), for levels of day-evening-night noise (Lden) of at least >=55 dB and >=65 dB. In addition to this, countries have to produce noise contour maps for roads, railways, airports and industries in urban agglomerations of more than 100 000 inhabitants in five dB bands starting at 55 dB for the day-evening-night period. The data set is provided in GPKG files, with all the reported noise contours in vector format by country or in the case of BE and DE by region, for Lden (day-evening-night noise level) and Lnight (nighttime noise level). Lden refers to an A-weighted average sound pressure level over all days, evenings and nights in a year, with an evening weighting of 5 dB and a night weighting of 10 dB and Lnight refers to an A-weighted average sound pressure level over all nights in a year.
Der Lärmindex LNight spiegelt die Lärmbelastung für die Nacht wider und wird für die Ausarbeitung von strategischen Lärmkarten verwendet. Diese Isophonen Karten stellen flächenhaft die Berechnungsergebnisse der Umgebungslärmkartierung 2022 an den Hauptverkehrsstraßen im Saarland dar. Entsprechend § 4 Abs. 4 der 34. BImSchV wird die Geräuschsituation für den LNight in den folgenden Isophonen Bändern mit einer Klassenbreite von 5 dB dargestellt: 45 dB(A) LNight 50 dB(A), 50 dB(A) LNight 55 dB(A), 55 dB(A) LNight 60 dB(A), 60 dB(A) LNight 65 dB(A), 65 dB(A) LNight 70 dB(A) sowie 70 dB(A) LNight. Die zentrale landesweite Strategische Lärmkartierung an Hauptverkehrsstraßen wurde im Saarland für die betroffenen und zuständigen Städte und Gemeinden durch den Saarländischen Städte- und Gemeindetag beauftragt. Das Ministerium für Umwelt, Klima, Mobilität, Agrar und Verbraucherschutz hat sich anteilig an den Kosten beteiligt und die Kartierung koordiniert.

Since 2002, time-lapse satellite gravimetry missions have successfully observed global time-variable mass transport. The GRACE (Gravity Recovery And Climate Experiment; Tapley et al., 2004, 2019) mission and its successor, GRACE-FO (GRACE-Follow On; Chen et al., 2022; Landerer et al., 2020), have almost continuously delivered monthly observations of the gravity field for more than two decades. As GRACE-FO approaches the end of its lifetime, new satellite gravity missions are planned for launch. For the continuation of the record, GRACE-C (GRACE-Continuity by NASA and the German Space Agency at DLR with support from GFZ, BMWK, BMFB, HGF and MPG ) is planned to be launched in 2028 in a near-polar orbit at an altitude of ~500 km. GRACE-C will be followed by the Next Generation Gravity Mission (NGGM) launched by the European Space Agency (ESA) in 2032 in an inclined orbit of 65–70 degrees at an altitude of ~400 km. In their overlapping period, these two satellite pairs form the Mass-change And Geoscience International Constellation (MAGIC). In the frame of the ESA SING (Studying the Impact of the NGGM and MAGIC Gravity missions) project (SING project website, 2026), extensive simulations have been performed to evaluate the added value of extended gravity field measurements in time with enhanced spatial and temporal resolution, and, reduced latency in data availability. Synthetic observations of the gravity field have been generated at Levels 2 and 3 for GRACE-C-like, NGGM and MAGIC satellite configurations using a closed-loop numerical simulator integrating instrument noise, background model errors, and realistic satellite orbits. The simulations utilize target Earth signals from the ESA Earth System Model ESM 2.0 (Dobslaw et al., 2015), including hydrology, ice, and solid Earth components. Two parameterisation strategies used in this study yield simulated gravity solutions of mean fields at 5-day and 30-day resolutions. The other two strategies result in direct estimation of the trend and annual signal (trendannual) and direct estimation of the long-term trend (trendonly). For each parameterisation strategy, the data products are separated into three levels (L2, L2P, and L3). L2 are Stokes coefficients of the simulated Earth’s potential provided separately for each mission scenario and expressed in the spherical harmonic basis in ICGEM format. L2p and L3 synthetic data represent simulated surface mass anomalies provided separately for each mission scenario and expressed in equivalent water heights over regular 1°*1° grids in NetCDF format. The L3 data were corrected for Glacial Isostatic Adjustment (GIA), while the L2p data were not. . The full description of the data and methods is provided in the data description publication (Schlaak et al. in prep.), and the file structure of this data set is fully described in the file inventory. The resolution of all data products (L2a, L2b, L2P, L3) for each mission scenario (GRACE-C-like, NGGM, MAGIC) depends on the simulation type described in Schlaak et al. (in prep.). For 5-daily solutions, the spatial resolution corresponds to ca. 285 km (d/o 70). For monthly solutions, the temporal resolution is 30 days, with a spatial resolution of ca. 166 km (d/o 120). Trend and annual signals (trend-and-annual solutions) have been estimated simultaneously over a period of 12 years (with 1-year increments) and a spatial resolution of ca. 150 km (d/o 130). For trend-only solutions, the spatial resolution is increased to 125 km, with trend estimates over 5 and 12 years. Additionally, empirical Variance-Covariance Matrices (VCMs) are provided for L2a and L3b data for the 5-daily and monthly simulation types, computed from Monte Carlo simulations (Schlaak et al., in prep.).
