# DeepCraters Lunar Craters Database 2020-07 This is a database of 117240 lunar impact craters larger than about 1 km in diameter. Craters were identified on 120m CE-1, 50m CE-2 DOM and DEM images captured by Chang’E-1 (CE-1) and Chang’E-2 (CE-2) orbiters. And that the formation Systems of new detected craters, 18,996 larger than 8km, are estimated. ## Method review The database of 117240 lunar impact craters are identified by the trained R-FCN model and the age of craters is estimated by a dual-channel classification model with the semisupervised method. (the details of method can be found in our paper[1]). ## Briefly Description The database contains two comma-delimited table files: `Lunar_Crater_Database_DeepCraters_2020.csv` and `Aged_Lunar_Crater_Database_DeepCraters_2020.csv`. > The first table is the detected craters larger than about 1 km in diameter, which contains 117240 craters with 5 common fields in each crater. What needs illustration is that the first 7009 craters contains additional 2 fields `Lat_new` and `Lon_new` because of the inaccuracy of the CE1 dataset. the details of each field are listed below: > - `Flags_data`: 'CE1' or 'CE2' indicats the crater detected from CE-1 or CE-2 data; > - `ID`: the index of craters; > - `Lat`: the latitude of crater center in degree; > - `Lon`: the longitude of crater center in degree; > - `Diam_km`: the diameter of crater in kilometer; > - `Lat_new`: the latitude of the corresponding crater in Robbins Lunar Crater Database[2] in degree; > - `Lon_new`: the longitude of the corresponding crater in Robbins Lunar Crater Database[2] in degree. > > The second table is the aged craters larger than 8 km in diameter, which contains 18996 craters with 6 fields in each craetr. And the first 5 fields are the same as in the first table, the last field `Age` indicates the system that the crater belongs to. > > - `Age`=1: pre-Nectarian System > - `Age`=2: Nectarian System > - `Age`=3: Imbrian System > - `Age`=4: Eratosthenian System > - `Age`=5: Copernican System -------- ## Note The diameter of craters detected by DeepCraters is slightly larger than the real size of the craters. ## Reference [1] Yang C , Zhao H , Bruzzone L , et al.

Paper III (Walker et al. 2024)

Data products used in 3-D CMZ Paper III, Walker et al. (2024). The full cloud catalogue is provided in tabular format, along with a full CMZ map showing the clouds and their assigned IDs. For each cloud ID in the published catalogue there are: - Individual cube cutouts from the MOPRA 3mm CMZ survey (HC3N, HCN, and HNCO). - Individual cube cutouts from the APEX 1mm CMZ survey (13CO, C18O, and H2CO). - Cloud-averaged spectra of the ATCA H2CO 4.83 GHz line. - PV slices of the ATCA H2CO 4.83 GHz line, taken across the major axis of the source. - Where applicable, there are mask files which correspond to the different velocity components of the cloud. In these cases, there are two mask files per velocity component, corresponding to the different masking approaches described in the paper.

中国逐日格点降水数据集V2（1960–2024，0.1°）

CHM_PRE V2数据集是一套高精度的中国大陆逐日格点降水数据集。该数据集基于1960年至今共3476个观测站的长期日降水观测数据，并纳入11个降水相关变量，用于表征降水的相关性。数据集采用改进的反距离加权方法，并结合基于机器学习的LGBM算法构建。CHM_PRE V2与现有的格点降水数据集（包括CHM_PRE V1、GSMaP、IMERG、PERSIANN-CDR和GLDAS）表现出良好的时空一致性。数据集基于63,397个高密度自动雨量站2015–2019年的观测数据进行验证，发现该数据集显著提高了降水测量精度，降低了降水事件的高估，为水文建模和气候评估提供了可靠的基础。CHM_PRE V2 数据集提供分辨率为0.1°的逐日降水数据，覆盖整个中国大陆（18°N–54°N，72°E–136°E）。该数据集涵盖1960–2024年，并将每年持续更新。日值数据以NetCDF格式提供，为了方便用户，我们还提供NetCDF和GeoTIFF格式的年度和月度总降水数据。
