This section presents some hints in MARS terms on how to name the different products. This is meant as a guideline and shows the keywords that select a specific data set, but not all keywords necessary to retrieve the data. Usually, operational archive data can be identified with the following MARS directives:
class = od domain = g expver = 1 |
Atmospheric high-resolution forecast
stream = oper |
Analysis
type = an |
Surface
levtype = sfc
Model levels
levtype = ml levelist = 1/to/137
Pressure levels
levtype = pl levelist = 1000/850/500...
Isentropic levels
levtype = pv/pt
Forecast
type = fc step = 12/to/240/by/12 |
First Guess
type = fg step = 6 |
Errors in Analysis
type = ea |
Errors in First Guess
type = ef |
Wave deterministic models
stream = wave |
Ensemble Forecast System
stream = enfo/waef |
Control Forecast
type = cf step = 12/to/360/by/12 |
Calibration/Validation Forecast
type = cv number = 1/2 step = 12/to/360/by/12 |
Perturbed Forecast
type = pf number = 1/to/50 step = 12/to/240/by/12 |
Forecast Probabilities
type = fp step = 24/to/240/by/24 |
Forecast mean probabilities
type = fp step = 144-168/144-240/192-240 |
Ensemble means
type = em/es |
Clusters
type = cm/es |
Tubes
type = tu step = 96 reference = 48/72/96 |
Extreme Forecast Index (EFI)
type = efi step=12/to/108/by/24 step=102-126/240/30-150/30-54/54-78/6-126/6-30/78-102 |
Trajectory forecast

Monthly Forecast
stream = mofc/wamf |
Monthly means
Deterministic
stream = mnth/wamo |
Climatology
