In this examine, the committee explores methods the nationwide climate provider (NWS) can reap the benefits of carrying on with advances in technological know-how and expertise to fulfill the demanding situations of the longer term. The predictions are interested by the objective yr 2025. simply because particular predictions in regards to the nation of technology and know-how or the NWS greater than 25 years sooner or later usually are not solely actual, the objective of this document is to spot and spotlight tendencies which are probably to persuade swap. The Panel at the highway Map for the longer term nationwide climate provider built an positive imaginative and prescient for 2025 according to advances in technological know-how and expertise.

Data from these spacecraft also enable the analysis and modeling of broad environmental phenomena and systems, of which weather and climate are components. Even the GPS satellites, which were intended for positioning and navigation, have important emerging uses in observing fundamental weather variables. To cover this wealth of satellite-based technologies, this section is divided into four categories of current and future systems: (1) geostationary and polar-orbiting satellites like those currently operated by NESDIS, (2) satellitebased radar systems, exemplified by the new tropical rainfall measuring mission (TRMM) satellite, (3) GPS (or similar positioning constellations) for occultation measurements, and (4) the NASA Earth observing system (EOS) and its potential future extensions.

Second, the observing and communication systems for alerting the public are still inadequate. The tornado detection and warning issue highlights the problem of detecting or forecasting small-scale phenomena of all kinds: detection and forecasting depend on observations at scales comparable to those of the phenomena. Partly as a result of the NWS modernization, but also because of regular improvements in observing systems, the temporal and spatial coverage and resolution of observations has continued to improve.

Current technologies include Doppler radars, such as the WSR-88D (commonly called NEXRAD) and wind profilers (see the section on Radar Systems below for details), microwave radiometers, acoustic sounders, and various lidar (light-wavelength radar) systems. These technologies provide profiles or path-integrated values of humidity, temperature, and wind, as well as quantitative measures of other weather variables, such as cloud liquid water. , 1997). , 1997). Tomographic inversion techniques applied to these profiles can be used to construct accurate and complete threedimensional water vapor fields for the atmosphere within 100 km (horizontal distance) of the station.
