About MetroClimate Observatory
MetroClimate Observatory is a powerful, browser-based climatological workstation designed for meteorologists, climate scientists, and data analysts who need to manage and analyze long-term meteorological records. It provides a comprehensive suite of tools for organizing station metadata, applying quality control flags, tracking missing data, and computing climate normals, anomalies, heatwave and rainfall indices. The application supports the import of real datasets, allowing users to work with actual observations rather than simulated data. With its intuitive dashboard, users can quickly visualize temperature anomalies, precipitation indices, and recent observations, making it an essential tool for climate monitoring and research.
Unlike typical weather apps, MetroClimate Observatory focuses on the professional needs of climate data management. It offers robust data quality control features, including the ability to flag suspect records, track missing data, and assess data completeness. Users can compute climate normals based on standard reference periods (e.g., 1991–2020) and generate anomaly time series to identify trends and extremes. The heatwave and rainfall indices help in assessing the frequency and intensity of extreme events, crucial for climate impact studies.
The application is built as a single-file HTML tool that runs entirely in the browser, with data stored locally using IndexedDB. This ensures privacy and offline functionality without the need for a server or sign-up. It is designed for both desktop and mobile use, with a responsive layout that adapts to different screen sizes. The interface is clean and professional, featuring a sidebar navigation for quick access to different sections such as Dashboard, Terminal, Stations, Records, QC Flags, Scenarios, and Reports.
MetroClimate Observatory is ideal for researchers, students, and professionals who need a lightweight yet powerful tool for climate data analysis. Whether you are monitoring local weather patterns, conducting academic research, or preparing climate reports, this app provides the necessary features to manage and analyze your data efficiently. Its focus on quality control and indices sets it apart from generic spreadsheet tools, making it a valuable addition to any climatologist's toolkit.

FAQ
Does MetroClimate Observatory require an internet connection?
No, the app runs entirely in your browser and stores data locally using IndexedDB. You can use it offline after loading the HTML file.
Can I import my own weather data?
Yes, you can import your own datasets in CSV format via the Terminal section. The app is designed to handle real-world data.
How are climate normals calculated?
Normals are calculated as the average of a variable over a specified reference period (e.g., 1991–2020). You can set the period in the Scenarios section.
What are QC flags?
Quality control flags indicate the status of each observation: 'pass' means data passed quality checks, 'fail' means it failed, and 'suspect' means it may be questionable. You can manually assign these flags.
Is there a sign-up or account needed?
No, there is no sign-up required. The app is fully client-side, so your data stays on your device.
Can I export my analysis results?
Yes, you can export charts and data tables to CSV format using the export buttons in the interface.
Is the app suitable for large datasets?
The app uses IndexedDB, which can handle large amounts of data, but performance may vary depending on your browser and device. It is optimized for moderate-sized datasets typical of climate studies.
