Current Solutions

Point to Zarr file --> user subsets

Goals

Getting a single point
Getting a bounding box
Query using time
Optimize data retrieval for temporal data
- Chunk by space
- Chunk by time
- Chunk by space + time

First Steps

What does it take to subset a point of data from a cloud hosted dataset?
- What dataset?
  - GFS!!
  - https://registry.opendata.aws/noaa-gfs-bdp-pds/#usageexamples
- Wave Watch + Buoy
Consider OGC API integration with xarray; see where pain points are
Try pygeoapi, but know there are existing issues
Testing

Defining IO

In - zarr dataset
Out
- Json, binary, or text
- Provide a tile
