24 alternatives to Experiments with Weather Data
I had been wanting to try experimenting with nowcasting since the death of Dark Sky and finally got around to it. This application essentially became a playground for me to experiment with various weather datasets and geospatial visualizations. Some interesting concepts that came from it: The nowcast is using pySTEPS optical flow under the hood: https://pysteps.readthedocs.io/en/latest/auto_examples/plot_.... This library is super cool. It bugged me that every radar visualization just gave you choppy snapshots in time, so I spent some time working on building a…

I was walking around New York last month during some light rain and noticed about half the people had umbrellas open. When the rain picked up a few minutes later, that number jumped closer to 80%. It got me thinking it'd be cool to track this somehow, so I built a website! I am taking a sidewalk livestream, feeding it into a YOLO model for people tracking, then sending a frame of each detected person to Gemini 2.0 Flash, which returns structured JSON about each person's clothing and if they're holding an umbrella. I also had fun making the site look like a TV weather channel. I showed some…

I've been working on this project for about 4 years. It began as terrain only because world wide elevation data was publicly available. I then added buildings from OpenStreetMap (crowd sourced) and more recently from Overture Maps data. Some computer vision/machine learning advancements [1] in the past few years have made it possible to estimate tree canopy heights using satellite imagery alone making it possible to finally add trees to the map. The data isn't perfect, but it's within +/- 3 meters of so. Good enough to give a general idea for any location on Earth. Happy to answer…

We just released a new weather website using all sorts of awesome web technologies. We use ModestMaps to show tiled, animated radar and satellite data, Raphael.js to show historical averages and record high/lows, and MapQuest's new Nominatim service sitting on top of OpenStreetMap to do location lookups. We're really proud of this site and would love to hear your feedback and to have try it out: http://preview.my-cast.com/

This is a service I've built to provide equirectangular cloud maps of the whole Earth, updated every 3 hours, for free. It's based on infrared and visible light data from EUMETSAT, processed to enhance the clouds and try to reduce the impact of surface temperatures on the final image. I built it because it's surprisingly hard to find these kinds of images in a format that's useful to developers and hobbyists. I was building a 3D ISS tracker and wanted to include live clouds but couldn't find anything good, so I got sidetracked, and here we are.

Over the weekend I was discussing the latest news relating to open weights with some of my non-techie friends. After 30 mins of waffling, I realised it is quite a long and interesting story, with many twists and turns. I've always wanted to create a 'long scroll' story, but have never found a suitable story to tell. This felt like a fun weekend project to undertake. The story itself doesn't have too many scroll effects (which is probably a good thing), it was more about trying to tell a story with a certain style that wouldn't really fit on my personal blog. Would love to get your feedback…

I miss Dark Sky, so I built my own weather app. Here's how GrayCloud works: * Raincast: minute-by-minute rain prediction and accumulation tracking for your exact location * Forecasts: 10 day forecasts use multiple high resolution sources and correct for bias at your location. * Alerts: rain starting, stopping, severe weather, daily summary and more * Widgets: home and lock screen widgets * Multi-platform: apple watch and mac apps I use NOAA and ECMWF models for core weather data and a custom model to compute rain accumulation and the next 60 minute radar movements. I also offer Apple…

I've been working on linecast, a free and open source collection of six terminal applications: weather, radar, sunshine, moon, tides, and maps. It's as if the Old Farmer's Almanac was built for Minitel. I made it because I'd been using the terminal a lot more over the past couple of years, I'm opinionated about weather forecast IA and design, and I liked the idea of making useful little terminal desk ornaments. The applications use ANSI color and Unicode braille characters rather than graphics. They reflow as the terminal is resized and derive their colors from your current terminal palette,…

Hey folks! This is a project that I've been working in my free time for the past few months. It's a news aggregator that uses AI to select relevant articles and summarize them. The default sources are frameworks and libraries' updates, popular HN topics, and languages' subreddits threads that make past a certain threshold. You can run a local instance (needs an OpenAI key) and customize it with your own sources, and adjust the prompt as well. The resulting website can be browsed at https://dev-radar.com/ My next experiment will be with local news. I'm building some feeds with…

As Dark Sky's API will stop working soon I thought I'd suggest a possible replacement. It is well known that most weather APIs just download data from NOAA and "repackage" them to JSON format. This means you will get data only for the nearest grid point which might be a few kilometers away and at a different altitude than your actual location. Meteosource combines more models (GFS, ECMW, UKMO, GEM,...). It compares individual models' performance to historical data and uses machine learning to create a single output. This approach minimises inaccuracies of individual models and feeds a…

Weather Flip▲11Hi HN, Weatherflip started as a side project and gradually became something I keep coming back to. I’ve always been slightly obsessed with weather. After living in the UK—with its poorly insulated homes—I was always chasing warmer climates. I built Weatherflip to answer a simple question: where in the world has the weather I want, either right now or later in the year? It uses historical data and short-term forecasts from yr.no, updated daily. Helpful for planning trips, moves, or just daydreaming. It’s still early. I’d love feedback—especially on what feels useful and what doesn’t.

This was posted before but I'm quite pleased to share a major update for https://oikolab.com. We now have available seven decades of hourly weather data starting from 1950 for any location in the world, thanks to the recent publication of ERA5 reanalysis data from European Centre for Medium-Range Weather Forecasts (ECMWF). ERA5 is gap-free, gridded dataset generated using data assimilation method (https://en.wikipedia.org/wiki/Data_assimilation), similar to NWP models but with the benefit of hindsight. As far as we're aware of, we're the first weather data…

Hi HN, I wanted to share my team's side project! We like to do R&D projects and investigate new areas, interesting problems, etc. This application visualises the dynamic interplay between space weather and our terrestrial power grid, focusing on Geomagnetically Induced Currents (GICs) across the UK. By visualising the magnetic field, induced electric field, and resulting GICs, users can identify vulnerable areas of the UK power network and assess the potential for operational disruptions during geomagnetic storms. We would love to get some feedback and expand this to cover more power grids…

This was my recent weekend project, aimed at teaching me JavaScript, a bit of HTML5, and (mostly) WebGL. The orbital data are from NASA JPL. I was inspired in part by this Flash app: http://www.dynamicdiagrams.com/wp-content/uploads/2011/04/orrery_2011_bce.swf, but wanted to do something in 3D. Coming from the games-dev world, this is my first introduction to web coding. The UI is jquery. I mostly used http://learningwebgl.com/blog for the 3D stuff. Being WebGL, it will work mostly on Chrome, Firefox 4 Beta. Forget about IE. I needed to figure out how to render text to the WebGL canvas - I…

Weather apps all claim to be accurate but never show their work. So I built a scoreboard that checks: it takes the forecasts each model published (ECMWF, GFS, ICON, AIFS and others, plus Apple Weather, Foreca, OpenWeather and Visual Crossing), waits for the weather to happen, and scores temperature, wind and rain against observations. A few things that surprised me: - AIFS performs very well, yet almost no commercial apps give you access to it or uses it in their blend (I suspect some do without disclosing it tho) - Foreca scores surprisingly well compared to other apps and raw models - ICON…

This is a small iOS app (iPad / iPhone) app I worked on that basically shows weather on a map (along with day/night info). Just something I made to quickly see what conditions are like all over the world. http://bit.ly/tUuEKB (app is free and ad-free, more just an experiment than anything else) Backend is in java (server) and perl (pulling data). More interesting than the app is perhaps the platform behind it. I hope to introduce other kinds of data to be seen on a map. Currently getting about 500-1000 downloads per day on iPad. Really just curious if people find anything unique or…
