Forecasts with an API
Happened across this website today: https://openweather.co.uk/
Maybe it's well-known, but new to me and an interesting example of the new breed of sites that provide forecasts with an API that is not just for those with deep pockets. Notable for being London-based and free to use for low-volume, individual access. In a nutshell: 'OpenWeather provides weather data for any location on the globe using a proprietary ML-powered hyperlocal forecasting model with resolution from 500 m to 2 km, globally.' More detail about the model process at: https://openweather.co.uk/technology.
Now to think how to make use of it. Would be nice to compare actual and forecast values eg temperature over time and apply some machine learning to fine-tune the forecast values, ie kind of like WXSIM but using AI to apply the corrections rather than Tom's careful analysis.

Re: Forecasts with an API
Isn't this the same site that CumulusMX has an interface with called OpenWeatherMap?

Re: Forecasts with an API
Very probably, in which case I'm obviously not up-to-date with this feature. But I guess I'm thinking more of being able to bring the forecast into software (does CMX do this? I'm not aware) and then being able to analyse forecast vs predicted and apply corrections.

Re: Forecasts with an API
No CumulusMX doesn't do that but a number of users including myself provide data to the Site.

Re: Forecasts with an API
OK, so this is pushing your data to the site in a similar way to WOW, WU etc, rather than pulling in the forecast data.

Re: Forecasts with an API
Like David, I have the API key and Station ID and am on their map and showing my CMX uploaded data. Haven't figured out what else to do with it though!
John's suggestion would be neat to compare the recent daily forecasts to actual (which I am doing semi-automatic now).
Enjoy,
Paul

Re: Forecasts with an API
But it does say:
Not sure if that would improve the predictions btw as PWS's can be very different from the official measurements. Especially wrt wind.
So if I interpret this well I would say it takes the basis of ECMWF and adjusts it every 10 minutes with weather station data. As such I think it does something like what John asks for CMX:The model uses a number of data sources - radars, models from global meteorological agencies (e.g., Met Office, NOAA, ECMWF), weather satellites, and a vast network of weather stations.
CMX does not do this but I think that site applies the corrections itself and adjusts the model of ECMWF (which is already very good) every 10 minutes on the basis of PWS's of which receives the data.But I guess I'm thinking more of being able to bring the forecast into software (does CMX do this? I'm not aware) and then being able to analyse forecast vs predicted and apply corrections.

Re: Forecasts with an API
It btw is a pretty extensive API returning the forecasts e.g. the 16 day forecast wich supplies basically everything you measure with your PWS and it updates every 10 minutes if I understand it well.
[EDIT:]
[EDIT:]
And btw I use a similar but less advanced API (scroll down to: API - Access to xml) in CUtils. For what it's worth.

No, you can pull the forecast from the site using the API

Re: Forecasts with an API
Yes, that was the main point of my post. It's not easy to find such a service without paying high commercial rates, though I think yr.no may do something similar. But I think other people were confirming that CMX pushes data to the map but does not import the forecast data.

Re: Forecasts with an API
It would be pretty cool if CMX did have something like this implemented?! A current conditions icon and text, with a 3 day outlook..

Re: Forecasts with an API
Yes, indeed. But I think one problem might be whether it could be done via just a single account at openweather, though maybe they might be open to discussion for a worthwhile cause like CMX. but another alternative might be for individual users to have their own (free) account and then requests for forecast data would be made via their own individual credentials.

Re: Forecasts with an API
I am a tad puzzled by this site as so far I've not found out how to sign up for a free account. I must admit I'm not a fan of providing my data to commercial organisations with nothing in return so I will not be doing that.
One thing I should point out is that WXSim now has the capability to use free ECMWF data as well as the GFS data it has always used. In my experience use of this ECMWF data has improved my WXSim forecasts although the mix ratio has not yet been completely settled on.
