Daily-averaged 3-D model outputs from a hindcast simulation of the Chesapeake Bay (1985-2025) with ROMS-ECB
A hindcast simulation of the period 1985-2025 was conducted with a 3-D numerical model of the Chesapeake Bay (ROMS-ECB). The dataset contains daily-averaged 3-D model outputs, with each calendar year in a separate sub-folder, and with 365 or 366 files per sub-folder. The outputs are in the NetCDF format (extension .nc), which is the standard file format of the modeling community and can be read/modified with many open-source languages/programs such as Python, R, GNU Octave. ROMS-ECB is described in the publications https://doi.org/10.1016/j.ecss.2025.109632 and https://doi.org/10.1029/2023MS003845 while the code is publicly available at https://github.com/myroms/. This work was supported by the National Science Foundation (collaborative grant 2148952). The hindcast was conducted by P.St-Laurent on the VIMS' HPC facilities in late 2025/early 2026. The authors acknowledge William & Mary Research Computing (https://www.wm.edu/it/rc) for providing computational resources and/or technical support that have contributed to the results reported within this dataset.

Abstract: This is a collection of datasets that show where and when precipitation exceeded average recurrence interval (ARI) thresholds at durations from 24-72 hours over the contiguous US (CONUS). Specifically, included are 100- and 1000-yr exceedances (i.e., precipitation accumulations with annual exceedance probabilities of ≤1% and ≤0.1%, respectively) from these precipitation datasets: NOAA's Stage IV analysis, 2002-2024 Parameter-Elevation Regressions on Independent Slopes Model (PRISM), 1981-2024 NOAA Multi-Radar Multi-Sensor (MRMS) system, 2018-2024 CONUS404 simulation, 1981-2024 Methods: The Stage IV, MRMS, and CONUS404 datasets were regridded to the 4-km latitude/longitude grid used by PRISM, using bilinear interpolation with the xESMF package, version 0.8.2 (Zhuang et al. 2023). This regridding was performed to allow for direct comparisons of spatial coverage of rainfall between datasets. Gridded precipitation estimates were compared to precipitation frequency estimates from NOAA Atlas 14, and all points exceeding the threshold for a given duration and ARI were recorded. Points were clustered into events using Density-Based Spatial Clustering of Applications with Noise (DBSCAN). An extensive set of automated and manual quality-control procedures were then applied to the exceedance points and events; details of these QC procedures are described in the Schumacher and Hill (2025) manuscript. TechnicalInfo: # Extreme precipitation datasets for the contiguous US, from gridded analyses and a convection-permitting model simulation Dataset DOI: [10.5061/dryad.jq2bvq8q2](https://doi.org/10.5061/dryad.jq2bvq8q2) ## Description of the data and file structure Lists of locations and times of points exceeding average recurrence interval thresholds (defined by NOAA Atlas 14) for three gridded precipitation datasets and the output of a regional climate simulation (CONUS404). ### Files and variables The naming convention for the included files is as follows: ``` _-__yh ``` `dataset` is one of: * stage4 (NOAA Stage IV analysis) * prism (PRISM analysis) * mrms (MRMS system) * conus404 (CONUS404 simulation). `startyear` is the first year included in the analysis (either 1981, 2002, or 2018), and `endyear` is the last year included in the analysis (either 2022 or 2024). `datatype` describes what is included in the file: * "removed_points" are the exceedance points that were removed by either automated or manual QC methods * "events" are the points retained and included in the analysis `ARI` is the average recurrence interval, either 100 or 1000 years. `duration` is 24, 48, or 72 hours. For durations of 48 and 72 hours, a second set of files is included with the suffix "nooverlaps". This is the dataset with overlapping time periods removed: any grid points in a dataset that had multiple exceedances within 3 days of each other at a given ARI and duration were identified. The date with the highest precipitation amount among these overlaps was retained in the dataset, and the others were removed. So, for example, the file named "stage4_2002-2024_events_1000y72h_edit_nooverlaps.csv" has the exceedances of the 1000-yr, 72-h ARI in the Stage IV dataset from 2002-2024. Overlapping time periods have been removed in this file. [In the file "stage4_2002-2024_events_1000y72h_edit.csv", points from overlapping time periods have not been removed.] The structure of each file is otherwise the same, as described below. Each row in a file represents one point on the 4-km grid that exceeded the ARI threshold for that duration. ##### Variables * time: Time in UTC, with the format "YYYY-mm-dd HH:MM:SS" * lat: Latitude in degrees * lon: Longitude in degrees * tp: Total precipitation (mm) * tp_minus_ari: Total precipitation minus the ARI threshold (mm) * tp_pct_of_ari: Total precipitation divided by the ARI threshold * event_num: The event number for this point, obtained from DBSCAN clustering. The event numbers are arbitrary (i.e., that an event was assigned number 1 or 5 has no special meaning.) ## Code/software Files are in comma-separated value (csv) format, which can be read by standard software packages such as Microsoft Excel, R, and the pandas python package. Software used to create these files and perform the QC procedures is in python, available online at [https://doi.org/10.5281/zenodo.22709265](https://doi.org/10.5281/zenodo.22709265) ## Access information Other publicly accessible locations of the data: * Interactive maps showing the data provided here can be found at: [https://schumacher.atmos.colostate.edu/precip_monitor/interactive.php](https://schumacher.atmos.colostate.edu/precip_monitor/interactive.php) Data was derived from the following sources: * Stage IV analyses were obtained from Du (2011). * PRISM analyses were obtained from [https://data.prism.oregonstate.edu](https://data.prism.oregonstate.edu). * MRMS data were obtained from a combination of sources, including a local archive maintained at Colorado State University, the Registry of Open Data on Amazon Web Services (AWS) ([https://registry.opendata.aws/noaa-mrms-pds](https://registry.opendata.aws/noaa-mrms-pds)), and the archive at the Iowa Environmental Mesonet ([https://mesonet.agron.iastate.edu/archive/mrms.php](https://mesonet.agron.iastate.edu/archive/mrms.php)).

{"Abstract":["# DeepCaImX## Introduction#### Two-photon calcium imaging provides large-scale recordings of neuronal activities at cellular resolution. A robust, automated and high-speed pipeline to simultaneously segment the spatial footprints of neurons and extract their temporal activity traces while decontaminating them from background, noise and overlapping neurons is highly desirable to analyze calcium imaging data. In this paper, we demonstrate DeepCaImX, an end-to-end deep learning method based on an iterative shrinkage-thresholding algorithm and a long-short-term-memory neural network to achieve the above goals altogether at a very high speed and without any manually tuned hyper-parameters. DeepCaImX is a multi-task, multi-class and multi-label segmentation method composed of a compressed-sensing-inspired neural network with a recurrent layer and fully connected layers. It represents the first neural network that can simultaneously generate accurate neuronal footprints and extract clean neuronal activity traces from calcium imaging data. We trained the neural network with simulated datasets and benchmarked it against existing state-of-the-art methods with in vivo experimental data. DeepCaImX outperforms existing methods in the quality of segmentation and temporal trace extraction as well as processing speed. DeepCaImX is highly scalable and will benefit the analysis of mesoscale calcium imaging. \n\n## System and Environment Requirements#### 1. Both CPU and GPU are supported to run the code of DeepCaImX.
