+# CoastalBench-preview
+
+ \[[**Paper**](https://openreview.net/pdf?id=h3EEUJaMLu)\]  \[[**GitHub**](https://github.com/spatialdatasciencegroup/CoastalBench)\]
+
+> This repository contains a 90-day subset of the full **CoastalBench** dataset, provided as a lightweight preview.
+
+
+## Dataset Overview
+
+- **Time span**: 2008-01-02 to 2008-04-01 
+- **Duration**: 90 days  
+- **Temporal resolution**: Half-hourly (48 time steps per day)  
+- **Spatial resolution**: 898 × 598  
+- **Vertical levels**: 12 (for 3D ocean features)  
+- **Data type**: `float16` (This preview uses lower precision compared to the original NetCDF files for reduced storage)
+
+
+## Variables
+
+### Ocean and Meteorological Features
+Each `.zarr` file contains 48 half-hourly time steps across 82 features, stacked along the first dimension.
+
+The 82 features include:
+- **3D variables** (each with 12 vertical levels, treated as 12 separate 2D channels):
+  - `u`: horizontal velocity (east-west)
+  - `v`: horizontal velocity (north-south)
+  - `w`: vertical velocity
+  - `temp` : temperature
+  - `salt` : salinity
+  - `AKs` : vertical mixing coefficient
+- **2D surface variables**:
+  - `zeta`: sea surface height
+  - `Pair`: surface air pressure
+  - `Qair`: specific humidity
+  - `Tair`: air temperature
+  - `rain`: rainfall rate
+  - `swrad`: shortwave radiation
+  - `lwrad`: longwave radiation
+  - `Uwind`: u-wind component
+  - `Vwind`: v-wind component
+- **Land-sea mask**:
+  - `mask`: binary mask (1 for ocean, 0 for land), included as the 82nd feature
+
+All features are stacked into a single 4D tensor:  `(features=82, height=898, width=598, time=48)`
+
+### River Inputs 
+Each river Zarr file contains 48 half-hourly time steps of 25 features across 4 river locations. These features include:
+
+- `river_transport`: river transport (1D)
+- `river_temp`: temperature at 12 depth levels
+- `river_salt`: salinity at 12 depth levels
+
+All features are stored in a 3D array with shape `(features=25, rivers=4, time=48)` and are temporally aligned with the ocean and meteorological data.
