Hello Rk Naresh, Sir!

Weather forecasting heavily relies on satellites for collecting data from space. Weather satellites have sensors and instruments to capture images and measure atmospheric variables such as temperature, humidity, and cloud patterns. Meteorologists then use this data to analyze and predict weather conditions with higher precision.

One of the Indian satellites used for weather applications is INSAT (Indian National Satellite System). It provides various meteorological services, including cyclone detection, weather forecasting, and climate studies. The INSAT system consists of a series of satellites in geostationary orbit.

The forecasters use data generated by the satellites around cloud motion, cloud top temperature, water vapour content that help in rainfall estimation, weather forecasting, and provide the genesis of cyclones and their direction.In a 24-hour period, the 14 orbits of each polar satellite provide two complete views of weather around the world. By having imagery of the whole globe, meteorologists are able to develop models to predict the weather out to five to ten days. INSAT -3D and INSAT-3DR satellite data are used in forecasting / monitoring weather. AI they are used for weather forecasting, navigation and communication. They can predict weather conditions, but they cannot change the weather. Satellites come in many shapes and sizes. But most have at least two parts in common - an antenna and a power source. The antenna sends and receives information, often to and from Earth. The power source can be a solar panel or battery.The five geostationary weather satellites all orbit over the equator at a height of about 35,800 km. Japan's GMS remains near longitude 140 east and cover Southeast Asia, Australia, and the Pacific Ocean. India's INSAT orbits at 75 East and covers southeast Asia, West Africa and the Indian Ocean. Geostationary satellites orbit the Earth at over 35 000 km above the Equator, spinning at the same speed as the Earth. This allows them to appear to hover over the same portion of the Earth and to provide constant monitoring of rapidly developing weather. With as much as 85% of your local weather forecast data coming from polar-orbiting satellites, their global observations are critical to both short-term and long-term forecasting. They also play a vital role in helping us to predict and prepare for severe weather events like hurricanes and blizzards.

What are you looking for that isn't in the Wikipedia article ( https://en.wikipedia.org/wiki/Weather_satellite )? Those in still in orbit ( active and decommissioned ) at https://www.n2yo.com/satellites/?c=3 some have decayed and not on the list. Your answer to your own question seems overly specific doesn't really address the broad theme requested.

Remote sensing used in weather forecasting goes far beyond just those platforms with supporting 'forecasting' as their primary mission - many other platforms and sensors also are combined contribute substantially, over temporal ranges from next-five-minutes 'nowcasting' to decadal climate predictions. An example of such fusion: "Enhancing Precipitation Estimates Through the Fusion of Weather Radar, Satellite Retrievals, and Surface Parameters" at Article Enhancing Precipitation Estimates Through the Fusion of Weat...

There are many very small firms which produce these sort of data fusion products for specific vertical markets like off-shore drilling, wind energy production, agribusiness, military, etc.

There are four main types of weather prediction we're going to discuss in this lesson: short-range, medium-range, long-range, and hazardous weather forecasting. The methods include persistence, climatologic, looking at the sky, use of barometer, now casting, use of forecasting models, analogue and ensemble forecasting. The prediction is made based on sliding window algorithm. The month wise results are being computed for three years to check the accuracy. The results of the approach suggested that the method used for weather condition prediction is quite efficient with an average accuracy of 92.2%. Weather Satellites are an important observational tool for all scales of NWS forecasting operations. Satellite data, having a global view, complements land-based systems such as radiosondes, weather radars, and surface observing systems. There are two types of weather satellites: polar orbiting and geostationary.

INRE: "There are two types of weather satellites: polar orbiting and geostationary" - three types, the Russians use a Molniya orbit: On the Use of Satellites in Molniya Orbits for Meteorological Observation of Middle and High Latitudeshttps://journals.ametsoc.org/view/journals/atot/7/3/1520-0426_1990_007_0517_otuosi_2_0_co_2.xml

And soon to be four types, tomorrow.io just launched the first two of a 30 radar satellite constellation ( https://en.wikipedia.org/wiki/Satellite_constellation ), which will consist of many differently inclined orbits ( like the GPS navigation constellation ): https://www.tomorrow.io/space/

And actually five types if one considers SOHO ( https://www.nasa.gov/mission_pages/soho/index.html ), which is in a halo orbit ( https://en.wikipedia.org/wiki/Halo_orbit ) that monitors solar wind inputs that drive the weather in the Earth's upper atmosphere, which affects things like the ozone hole ( https://polarjournal.ch/en/2021/08/31/solar-winds-trigger-ozone-depletion-in-the-mesosphere/ ).

Satellite imaging can detect things such as wind patterns and temperature changes, which can help meteorologists make more accurate predictions about future weather. For example, satellite images can detect changes in the amount of moisture in the atmosphere and the temperature at different altitudes. There are four main types of weather prediction we're going to discuss in this lesson: short-range, medium-range, long-range, and hazardous weather forecasting. Geostationary satellites orbit the Earth at over 35 000 km above the Equator, spinning at the same speed as the Earth. This allows them to appear to hover over the same portion of the Earth and to provide constant monitoring of rapidly developing weather. Weather Satellites are an important observational tool for all scales of NWS forecasting operations. Satellite data, having a global view, complements land-based systems such as radiosondes, weather radars, and surface observing systems. There are two types of weather satellites: polar orbiting and geostationary. Because they stay above a fixed spot on the surface, they provide a constant vigil for the atmospheric "triggers" for severe weather conditions such as tornadoes, flash floods, hail storms, and hurricanes. Geostationary satellites are the bread and butter satellites for the meteorologist. The forecasters use data generated by the satellites around cloud motion, cloud top temperature, water vapour content that help in rainfall estimation, weather forecasting, and provide the genesis of cyclones and their direction. INSAT-3D is designed for enhanced meteorological observations, monitoring of land and ocean surfaces, generating vertical profile of the atmosphere in terms of temperature and humidity for weather forecasting and disaster warning. It is used for communication such as long distance transmission of television programme, radio, telephone calls and internet. It is used for surveying natural resources of the earth like minerals, agricultural crops etc. It is used for spying for military papooses.Polar-orbiting satellites orbit at low-altitude around the North or South Pole and monitor the entire planet over the course of 10 days to 1 month. The information and data from these satellites are used in weather forecasting

@Rk Naresh In a addition to the six types of space platforms, if classified basically by gravitational trajectories, there is a seventh.

Suborbital sensors on sounding rockets - series of these were launched by the military launched from sites scattered around the planet, to monitor radio-isotopes spread by wind in the upper atmosphere, some above Kármán line at 62 miles (100 kilometers), not so much after the Atmospheric Test Ban Treaty. Because of the military nature of these, I can only find oblique references.

But there are now several prototype efforts in progress ( https://www.forbes.com/sites/brucedorminey/2023/03/23/nasa-sounding-rockets-hunt-hurricane-like-winds-at-the-edge-of-space/?sh=7da2794f718c ) ... "The main science drivers are to better understand the atmospheric “fluid” just above 100km and how strong winds and wave action mix it, Gerald Lehmacher, a professor of physics at Clemson University in South Carolina and principal investigator for VortEx, told me via email. We hope that the results from our experiment will improve our ability to model and forecast the upper atmosphere conditions, he says. ... Even so, buoyancy waves and the winds they generate at altitudes of 80km to 140km are thought to drive much of our planet’s global weather patterns. But until now, researchers have had a difficult time in obtaining real time, in situ data at such high altitudes."

If that is the target range, the sensor packages will activate below and above, so probably cross the Kármán line.

So, it would be a Solid Seven of types.
