The CIMSS Tropical Cyclone webpage helps achieve these goals by providing near real-time imagery, derived atmospheric analysis products, and TC intensity estimates from a variety of different satellite platforms for global analysis of TCs and their surrounding environments. Many of the products from CIMSS are developed specifically for use by TC forecasters worldwide to provide unique information in support of their specific TC forecasting missions.

Statement: Measurements, images and other data have been obtained by the following means:
1. The Advanced Dvorak Technique (ADT) utilizes longwave-infrared, temperature measurements from geostationary satellites to estimate tropical cyclone (TC) intensity.
2. The Advanced Microwave Sounding Unit (AMSU). The AMSU consists of two instruments, AMSU-A and AMSU-B. These instruments are capable of measuring the brightness temperatures over a number of layers of the atmosphere.
3. The CIMSS Satellite Consensus (SatCon) product blends tropical cyclone intensity estimates derived from multiple objective algorithms to produce an ensemble estimate of intensity for current tropical cyclones worldwide. The SatCon algorithm uses individual ADT, CIMSS AMSU, and CIRA AMSU intensity estimates utilizing a statistically-derived weighting scheme which maximizes/minimizes the strength/weaknesses of each technique to produce a consensus estimate of the current tropical cyclone intensity.
4. The Morphed Integrated Microwave Imagery at CIMSS (MIMIC) product provides a radar-like visualization of the evolution of TC structure using advanced image morphing algorithms.
5. The MIMIC-TPW product presents total precipitable water over the ocean, retrieved from SSMI and AMSR-E microwave sensors.

The main questions facing tropical cyclone (TC) forecasters are accurately determining the current intensity of the storm, the future intensity of the storm, and where the storm will be in the future. Data obtained from satellites are ideal for helping to provide answers to these questions due to their ability to provide nearly constant and total coverage of the tropics in space and time.
