From Earth to Space: The Evolution of Weather Forecasting
Weather forecasting has come a long way since the first recorded weather observations were made in ancient Babylon around 650 BC. Early methods of predicting the weather involved observing natural phenomena such as the movement of clouds, wind direction and barometric pressure. However, with advancements in technology, particularly in the field of space-based weather forecasting, we have been able to revolutionize our ability to predict and prepare for extreme weather events.
Launching Satellites into Orbit
In 1960, the first successful satellite launch paved the way for space-based weather forecasting. The TIROS-1 (Television Infrared Observation Satellite) was launched by NASA, which provided television images of cloud cover over Earth's surface. This marked a significant breakthrough in meteorology as scientists could now observe global atmospheric patterns that were previously unknown.
Advancements in Technology
Since then, there have been numerous advancements in technology that have helped improve space-based weather forecasting accuracy and reliability. One such example is Doppler radar technology which uses radio waves to detect precipitation and wind speed at different altitudes within a storm system.
Collaboration among Nations
Collaboration among nations has also played an important role in advancing space-based weather forecasting capabilities. The European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) launched its first satellite Meteosat-1 back on November 23rd 1977 with cooperation from France’s National Centre for Space Studies (CNES). Since then it has launched several more satellites including Meteosat Third Generation (MTG).
Similarly NASA partnered with NOAA’s geostationary operational environmental satellite-R series (GOES-R) program that launched four advanced satellites between November 2016 and March 2018. These satellites provide high-resolution images of Earth's surface every 30 seconds, drastically improving the accuracy and timeliness of severe weather warnings.
The Future of Space-Based Weather Forecasting
The future of space-based weather forecasting looks promising with several new technologies and initiatives on the horizon.
One such initiative is the International Space Station's (ISS) Total and Spectral Solar Irradiance Sensor (TSIS-1) mission which will measure solar irradiance, or the amount of energy emitted by the sun. This data will be used to improve our understanding of how variations in solar activity affect Earth's climate and weather patterns.
Finally, scientists are also exploring ways to use nanosatellites or CubeSats for space-based weather forecasting applications. These small satellites can be launched quickly and at a lower cost than traditional larger satellites. They have also been used for imaging earth from near-space as well as monitoring atmospheric conditions such as temperature profile measurement.

Advancements in Satellite Technology
Advancements in satellite technology have led to significant improvements in weather forecasting accuracy over recent years. For instance:
- GOES-R series provides high-resolution images every 30 seconds from four advanced satellites helping predict severe storm conditions accurately.
- European Centre for Medium-Range Weather Forecasts’ Meteosat Third Generation (MTG) offers a 30-second update time for images of Earth's surface. It also has the capability to track severe weather patterns like hurricanes before they make landfall, saving lives and property damage.
Future of Satellites in Weather Forecasting
The future of space-based weather forecasting looks bright with several new initiatives that will improve satellite capabilities even further.
One such initiative is NASA's Global Precipitation Measurement (GPM) mission which was launched in 2014. It uses a network of satellites to monitor precipitation patterns worldwide, providing critical information on water availability and flood risks in real-time.
Another exciting development is the use of CubeSats or nanosatellites for space-based weather forecasting. These small satellites can be launched quickly and at a lower cost than traditional larger satellites while still providing valuable data. For instance, Spire Global Inc., uses over 100 CubeSats deployed in low-Earth orbit to provide data on atmospheric conditions such as temperature profile measurement from different altitudes within our atmosphere.
