A New Way to Work With NetCDF Data 🌍

NetCDF is one of the most widely used formats in meteorology, climate science, environmental monitoring, oceanography, and remote sensing.

But despite its power, NetCDF files can be difficult to preview, explore, or inspect without writing code or loading heavy scientific libraries.

With ParquetReader’s new native NetCDF support, you can now upload, view, filter, and query NetCDF datasets instantly — all from a simple, lightweight, browser-based interface.

Why We Built It 💡

Many teams rely on NetCDF for large gridded datasets, multi-dimensional time series, and model outputs. Yet everyday tasks — like checking variables, extracting a slice, or validating a dataset — often require custom scripts or complex tooling.

We wanted to change that by making NetCDF files instantly accessible and easy to explore for anyone, regardless of technical background.

ParquetReader now provides a fast, modern way to understand NetCDF content without spinning up Python notebooks or specialized workflows.

How It Works 🔍

Upload any .nc or .nc4 file — no configuration needed.

ParquetReader automatically detects variables, dimensions, coordinate grids, and attributes.

Multi-dimensional arrays (for example: time × lat × lon) are normalized into a tabular structure so you can explore them just like any other dataset.

You can quickly inspect metadata, preview variable values, and navigate through complex structures with a clean UI.

Ideal for Radar, Forecasting, Climate & Environmental Data 🌦️🌡️🌊

NetCDF is used across a wide range of scientific and operational domains:

- Radar and precipitation fields

- Weather model outputs

- Climate projections and reanalysis

- Atmospheric profiles

- Ocean and marine datasets

- Environmental sensor grids

ParquetReader turns these datasets into fast, searchable, filterable tables — ideal for inspection, quality checks, validation, extraction, and exploratory analysis.

Step 1 — Upload Your NetCDF File 📤

Drag your NetCDF file into ParquetReader and it’s instantly analyzed.

Variables, shapes, coordinates, and attributes appear automatically.

There’s no need for specialized software or heavy scientific environments.

Step 2 — Explore Variables & Dimensions 📊

Browse variables with clear previews and automatic dimension handling.

View slices of multi-dimensional arrays in a clean, tabular format.

Understand exactly what’s inside your dataset before running any transformations.

Step 3 — Query Your Dataset Instantly ⚡

Every NetCDF file becomes a queryable dataset in the SQL editor.

You can filter, aggregate, sort, or slice your data using simple SQL — even for large files.

Example:

`SELECT time, AVG(value) FROM dataset WHERE lat BETWEEN 52 AND 53 GROUP BY time ORDER BY time;`

Perfect for quick analysis, summaries, or extracting the exact subset you need.

Step 4 — Export Data in Seconds 🔄

Export any filtered subset of your NetCDF data as CSV or JSON.

Ideal for downstream workflows, dashboards, BI tools, machine learning pipelines, or sharing data slices with colleagues.

No manual conversions or scripting required.

Built for Both Online and Self-Hosted Deployments 🔒

You can use NetCDF support on ParquetReader Online, or deploy the Self-Hosted Edition inside your own infrastructure.

The self-hosted version runs entirely within your environment, making it suitable for organizations with strict privacy, compliance, or data-sovereignty requirements.

No external APIs, no data sharing, and full control over your setup.

Why This Matters 🚀

NetCDF has traditionally been powerful but challenging to explore quickly.

With ParquetReader, NetCDF becomes:

- Easy to preview

- Easy to navigate

- Easy to analyze with SQL

- Easy to share as clean subsets

- Fast even for large grids and long time series

It’s a modern, user-friendly way to work with complex scientific datasets — without specialized software or heavy workflows.
