Die Messungen im erweiterten Festpunktnetz zur Erfassung der Gebirgsbewegungen im Grubengebaeude werden fortgesetzt. Die Untersuchungen zu einer moeglichen Subrosion oder einem Salzauftrieb am Asse-Sattel werden durch die Einrichtung einer ca. 1 km langen Festpunktlinie entlang der neuen Eisenbahntrasse erweitert. Zur Erkundung der Salzstruktur werden geophysikalische Methoden eingesetzt. Die geologischen Detailuntersuchungen fuer die versuchsweise Einlagerung von hochaktiven Abfaellen werden fortgefuehrt. Im Rahmen der Umgebungsueberwachung werden Proben aus der Umgebung und aus Kontrollbereichen gammaspektroskopisch analysiert.

The TWS anomaly grids are provided in NetCDF format containing four different variables: 1) 'tws': gravity-based TWS 2) 'std_tws': gravity-based TWS standard deviations 3) 'leakage': spatial leakage contained in 'tws' 4) 'model_atmosphere': background model atmospheric mass These Level-3 products are visualized at GFZ's web portal GravIS (https://gravis.gfz.de).

Post-processed GRACE/GRACE-FO spherical harmonic coefficients of COST-G RL02 Level-2 GSM products representing an estimate of Earth's gravity field variations during the specified timespan. Post-processing steps comprise: (1) subtraction of a long-term mean field; (2) optionally, decorrelation and smoothing with VDK filter (anisotropic filter taking the actual error covariance information of the underlying GSM coefficients into account, see Horvath et al. (2018)); (3) replacement of coefficients C20 and C30 (only for the months within the period from 2016/11 through 2017/06) and its formal standard deviations by values estimated from a combination of GRACE/GRACE-FO and Satellite Laser Ranging (SLR); (4) subtraction of linear trend caused by Glacial Isostatic Adjustment (GIA) as provided by a numerical model; (5) insertion of geocenter coefficients (C10, C11, S11); and (6) removal of estimated aliased signal of the S2 tide (161 days period). These coefficients represent signals caused by water mass redistribution over the continents and in the oceans. These post-processed GRACE/GRACE-FO GSM products are denoted as Level-2B products. There are multiple variants of Level-2B products available that differ by the characteristics of the anisotropic filter applied. These variants are distinguishable by the following strings in the product file names: - 'NFIL': Level-2B product is not filtered - 'VDK1': Level-2B product is filtered with VDK1 - 'VDK2': Level-2B product is filtered with VDK2 - 'VDK3': Level-2B product is filtered with VDK3 - 'VDK4': Level-2B product is filtered with VDK4 - 'VDK5': Level-2B product is filtered with VDK5 - 'VDK6': Level-2B product is filtered with VDK6 - 'VDK7': Level-2B product is filtered with VDK7 - 'VDK8': Level-2B product is filtered with VDK8 The individual auxiliary data sets and models used during the post-processing steps mentioned above are provided as well (in the aux_data folder): - 'GRAVIS-2B_COSTG_0200_2002095-2020091_NFIL_0001.gz': Long-term mean field calculated as unweighted average of the 183 available GFZ RL06 GSM products in the period from 2002/04 through 2020/03 - 'GRAVIS-2B_COSTG_0200_GRACE+SLR_LOW_DEGREES_0001.dat': Time series of coefficients C20, C30, C21 and S21 estimated from a combination of GRACE/GRACE-FO and SLR - 'GRAVIS-2B_COSTG_0200_GIA_ICE-6G_D_VM5a_0001.gz': Model from Peltier et al.

GRACE/GRACE-FO Level-3 product based on COST-G RL02 Level-2B products (Dahle & Murböck, 2025) representing Ocean Bottom Pressure (OBP) variations provided at 1° latitude-longitude grids as defined over ocean areas. The OBP grids are provided in NetCDF format containing seven different variables: 1) 'barslv': gravity-based barystatic sea-level pressure 2) 'std_barslv': gravity-based barystatic sea-level pressure standard deviations 3) 'resobp': gravity-based residual ocean circulation bottom pressure 4) 'std_resobp': gravity-based residual ocean circulation bottom pressure standard deviations 5) 'leakage': apparent gravity-based bottom pressure due to continental leakage contained in 'resobp' 6) 'model_ocean': background-model ocean circulation pressure 7) 'model_atmosphere': background-model atmospheric surface pressure These Level-3 products are visualized at GFZ's web portal GravIS (https://gravis.gfz.de).

Spherical harmonic coefficients that represent the sum of the ATM (or GAA) and OCN (or GAB) coefficients during the specified timespan. These coefficients represent anomalous contributions of the non-tidal dynamic ocean to ocean bottom pressure, the non-tidal atmospheric surface pressure over the continents, the static contribution of atmospheric pressure to ocean bottom pressure, and the upper-air density anomalies above both the continents and the oceans. The anomalous signals are relative to the mean field from 2003-2014.
The dataset contains mean masses of butterfly species and different noctuid moth size classes collected between end of May and beginning of September 2020 using different Malaise traps in three low mountain range regions in Germany: Hunsrueck (National Park Hunsrueck-Hochwald), Spessart (Rhine-Main-Observatory) and Steigerwald. The butterflies were stored in alcohol after their capture and were weighed with a precision scale (0.001 g) after shaking them briefly to remove residual alcohol. Part of the specimen collected was used for DNA-metabarcoding. The other part was deposited in the specimen collection of the Environmental Campus Birkenfeld (Trier University of Applied Sciences).
The dataset contains abundance data of butterfly species and noctuid moths in five different Malaise trap types which were placed as a defined set each on a meadow and a forest clearing site in three regions of Germany: Hunsrueck (National Park Hunsrueck-Hochwald), Spessart (Rhine-Main-Observatory) and Steigerwald. Abundances of noctuid moths were recorded per size class. Butterfly data covers weeks from the end of May to the beginning of September 2020. The data was collected to perform a trap comparison between the Malaise trap types which were a large Townes trap with a white roof, a large Townes trap with a black roof, a smaller Townes trap with a black roof, a dark Bartak trap with a conventional capture bottle and a dark Bartak trap with an eclector bottle. Part of the specimen collected was used for DNA-metabarcoding. The other part was deposited in the specimen collection of the Environmental Campus Birkenfeld (Trier University of Applied Sciences). With our study, we aimed to reveal possible differences in butterfly species capture with different types of Malaise traps and the implications for total insect biomass of the samples.
