Model & satellite data
Synoptic analysis
Simple analysis based on observed synoptic data provides an instantaneous snapshot of state of atmosphere
-
-
Model data
Advantages
-
Raw observations are smoothed during interpolation onto model grid- helps remove bias from non-representative measurements
-
-
-
NWP
Data assimilation= the inclusion of observations in the previous forecast- takes large part of time within a forecast cycle (6 hours)
-
-
-
-
-
Parameterisation
Processes that are parameterised in global model: turbulence, convection and cloud microphysics
-
-
Reanalysis
A reanalysis uses the same data assimilation techniques and NWP model to produce a comprehensive set of past weather
-
-
Widely used in research for: climatological studies, model initialisation fields in data sparse/ upper level areas, and providing boundary conditions for regional scale modelling studies
-
Sensors
Passive
-
E.G: Visible, infrared or microwave data
-
Satellite data retrievals used to make estimates of: SST, Wind speeds, land use, amounts of chemicals
