Frequently Asked Questions
What is CLIMA TERRA?
CLIMA TERRA is a global climate and environmental experience in PWA format that turns open data into visual, short and useful messages.
What is it for?
It helps people better understand how temperature, UVI, humidity, wind, rain and air quality may influence their daily context.
Who created CLIMA TERRA?
It was created by Alfonso Rodríguez (@alfonsoAIData), from Arcos de la Frontera, Spain, as part of his digital experiences portfolio.
Why was it created?
It was created to translate open climate and environmental data into clear support messages: caring without ordering or alarming.
How is it different from a conventional weather app?
It does not focus on accumulating forecasts, tables or data. Its value is interpreting data and turning it into simple daily messages.
What does PWA mean?
It means Progressive Web App: it works from the browser and, on compatible devices, can be installed as a web app without an app store.
What data does it show?
It shows temperature, ultraviolet index/UVI, humidity, wind, rain or rain probability and air quality/AQI.
What does using open data mean?
It means CLIMA TERRA relies on accessible sources such as Open-Meteo and OpenStreetMap / Nominatim to retrieve and interpret climate, environmental and location information.
Is CLIMA TERRA free?
Yes. CLIMA TERRA is free, requires no registration and includes no user accounts or payments.
Is it independent?
Yes. It is an independent project by Alfonso Rodríguez. It is not an official service and does not represent the data sources it uses.
Which devices does it work on?
It is designed for mobile, tablet and desktop through a modern browser. PWA installation depends on the operating system, browser and device settings.
How does it help interpret temperature?
Temperature is interpreted with other factors to talk about heat, cold, hydration and thermal feeling without assuming a specific activity.
How does it help interpret UVI?
UVI helps understand solar radiation. When it is high, CLIMA TERRA prioritizes messages such as shade and sun protection.
How does it help interpret humidity?
Humidity is expressed as dry, balanced, heavy or loaded atmosphere to avoid confusion with air quality.
How does it help interpret wind?
Wind is presented as calm, breeze, gusts or outdoor caution to guide outdoor experience without imposing decisions.
How does it help interpret rain?
Rain is translated into daily preparation: dry day, changing sky, umbrella, covered areas or outdoor caution.
What does AQI mean?
AQI means Air Quality Index. In CLIMA TERRA, the scale used shows values from 0 to 50 as good air quality.
Why do messages change according to several factors?
Because the same condition may feel different depending on time of day, sun, humidity, wind, rain or air quality. CLIMA TERRA cross-reads data to avoid contradictions.
Can it help with more conscious daily decisions?
Yes. It can provide context for sun exposure, outdoor activity, hydration or daily preparation, always using personal judgement.
Does CLIMA TERRA replace an official forecast or alert?
No. It does not replace official forecasts, emergency alerts, official meteorological services, medical recommendations, diagnoses or professional decisions.
Does CLIMA TERRA store personal data?
It does not request registration, create accounts or collect personal information. It may store minimal browser preferences such as language.
Why does CLIMA TERRA request my location?
It uses it to retrieve climate and environmental conditions around you. Permission is controlled by the browser or operating system.
What happens if I do not allow location access?
You can try again or manually search for any city or place. The main experience remains available.
Can I manually search for another place?
Yes. Search remains available whether or not you share your location.
Can it open a specific location from a link?
Yes. A link can include latitude, longitude, a visible place name and language. Those coordinates are used for the current query and are not stored.
Do the data correspond exactly to the selected point?
Not necessarily. They may come from a weather or environmental grid associated with the area around the coordinates.
What do the Temperature, Ultraviolet index and Air quality panels provide?
They add context and general guidance. The air-quality panel explains the difference between US AQI and PM2.5 and separates Open-Meteo data from CLIMA TERRA's interpretation and reference sources.
Are the recommendations medical advice?
No. They are general guidance and do not replace professional advice, official alerts or emergency recommendations.
Who provides the current data?
The current sources and the exact role of each service are documented in Sources and transparency.
What is the role of the official NASA, EPA and WHO references?
NASA provides general background on air quality, the U.S. EPA documents the US AQI system, and WHO provides general context on air pollution and health. None of these organisations supplies CLIMA TERRA’s real-time data, calculates its displayed values, validates or sponsors the project.
What does PM2.5 mean?
It is the concentration of fine particles with an aerodynamic diameter of 2.5 micrometres or less, expressed in µg/m³.
What is the difference between AQI and PM2.5?
US AQI is a general air-quality index. PM2.5 is a specific concentration of fine particles. They are displayed together but are not equivalent.
