title: Monthly Northern Hemisphere Tropospheric Analyses

description: The DSS assembled this long time-series collection of monthly gridded Northern Hemispheric data from the output of various operational models. Monthly mean grids are available separately for 00Z and 12Z (or 03Z and 15Z in the earlier years). Parameters include temperature, geopotential height, and u- and v- wind components at various tropospheric levels, and sea-level pressure and surface temperature. The data are presented on a 47-by-51 north polar stereographic grid with a 381 kilometer resolution (at 60N).We continue to update this dataset mainly for users who have used it in the past and wish to continue receiving the same format. Particularly from April 1997 on, the grids in this dataset are derived from NCEP operational outputs that have a better resolution that what is offered here, so please consider those other more-recent datasets especially if your needs are for data from the late 1990s onward.

title: Monthly Northern Hemisphere 2.5-degree Tropospheric Analyses for 1946-1972

description: This dataset contains a time-series collection of monthly Northern Hemisphere tropospheric data on a 2.5-degree latitude/longitude grid. These grids were created by DSS from the grids of ds085.0 [http://rda.ucar.edu/datasets/ds085.0/], which have a resolution of five degrees. The intermediate points of the grids in this set were interpolated from the existing surrounding gridpoints using a 16-point Bessel interpolation scheme.
DOI: 10.5065/czqh-k835
title: Monthly Northern Hemisphere 5-Degree Tropospheric Analyses, continuing from April 1947

description: This dataset contains a time-series collection of monthly mean gridded Northern Hemisphere tropospheric data on a 5-degree latitude/longitude grid. This collection was assembled and computed by DSS from the daily grids of various operational models and meteorological projects. The daily grids are located in ds195.1 [http://rda.ucar.edu/datasets/ds195.1/].

title: NCEP/NCAR Global Reanalysis 8-day Forecast Products

description: This data set contains forecast products from the NCEP/NCAR Reanalysis Project. The resolution of the Reanalysis Forecast Model is T62 (209 km) with 28 vertical sigma levels. Every five days, beginning with 00Z 01 January, an 8 day forecast run is made. The initial time and outputs for every 12 hours are saved from this run. Pressure level and special level data are archived on the 2.5 by 2.5 latitude-longitude grid and flux fields are archived on the 192 by 94 Gaussian grid. Details on variables included are available elsewhere. Some special periods will be analyzed more than once to provide data for special research studies. For example, a special run of 1979 was made excluding most satellite inputs. This run could be used for evaluating the impact of satellite data on the forecasts. See DS090.0 [https://rda.ucar.edu/datasets/ds090.0/]for analysis and first guess fields. All data files for January 1948 to October 2005 are available as of 2005DEC29.

title: NCEP/NCAR Reanalysis Monthly Mean Subsets (from DS090.0), 1948-continuing

description: The monthly means of NCEP/NCAR Reanalysis (R1) products, archived in ds090.0 [http://rda.ucar.edu/datasets/ds090.0/] dataset, are extracted and reorganized into subgroups in this dataset. The groupings try to combine like and/or commonly used parameter-level data together. There are also subgroups for each of the four diurnal monthly means (means of 00Z, 06Z, 12Z, and 18Z separately).The data files are in WMO GRIB format. Both the monthly means and their variances are in the same file but in different GRIB records. Examples of separating monthly means from variances are shown in this guide [http://rda.ucar.edu/datasets/ds090.2/docs/how2use_grads.txt].All subgroups will be available on line under data [http://rda.ucar.edu/datasets/ds090.2/#access]. The ones that are not on line yet will be moved over upon request.

title: NCEP/DOE Reanalysis 2 (R2)

description: This dataset contains products from the NCEP/DOE Reanalysis 2 (R2) Project. The resolution of the R2 model is the same as NCEP/NCAR Reanalysis (R1) project, T62 Gaussian grids with 28 vertical sigma levels. The output fields are saved 4 times a day as in R1. The main objective of the R2 project is to correct known errors in the R1 project and update the parameterizations of the physical processes. Improvements are seen in surface flux fields, hydrological budget, short wave radiation flux, etc. There are also drawbacks found in the outgoing longwave radiation over tropical warm pool and upper-level tropical moisture. R2 plans to reanalyze the data starting from 1979 and going forward only.The main R2 products archived at NCAR consitute of 6 subgroups: pressure level analysis, sigma level analysis, flux term analysis, diagnostic analysis and 6-hour forecasts of flux term and diagnostic terms. All data files are in GRIB format and archived by month.This dataset is updated once a month. Limited amount of recent data are also available at NCEP (https://ftp.cpc.ncep.noaa.gov/wd51we/reanalysis-2/). Earth System Research Laboratory's Physical Sciences Division of NOAA has the same data in netCDF format at https://www.esrl.noaa.gov/psd/data/gridded/data.ncep.reanalysis2.html [https://www.esrl.noaa.gov/psd/data/gridded/data.ncep.reanalysis2.html].

title: NCEP Climate Forecast System Reanalysis (CFSR) Selected Hourly Time-Series Products, January 1979 to December 2010

description: The National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) was initially completed over the 31-year period from 1979 to 2009 and has been extended to March 2011. NCEP has created selected time series products at hourly temporal resolution by combining either 1) the analysis and one- through five-hour forecasts, or 2) the one- through six-hour forecasts, for each initialization time. Please note that NCEP only created time series for parameter/level combinations that they thought would be most useful to users. Time series that do not exist in this dataset can be created from the full 6-hourly products dataset at https://rda.ucar.edu/datasets/ds093.0/ [https://rda.ucar.edu/datasets/ds093.0/]. For more information about CFSR in general, please see this page [https://cfs.ncep.noaa.gov/cfsr/]. For data to extend CFSR beyond March 2011, please see the Climate Forecast System Version 2 (CFSv2) datasets.

title: ECMWF IFS High-Resolution Operational Forecasts

description: ECMWF has implemented a significant resolution upgrade and methodology for high-resolution forecasts (HRES) and ensemble forecasts (ENS) beginning January of 2016. HRES is now performed via a transform grid with a nominal grid point spacing of 9 kilometers (0.08 degrees), and is carried out with IFS (Integrated Forecast System). Improvements in computational efficiency and effective resolution have been brought about by implementing a triangular cubic octahedral reduced Gaussian grid in which the shortest spatial wavelength is represented by at least four grid points anywhere on the globe, as opposed to the former linear arrangement whereby the shortest wavelength was represented by two grid points, while at the same time retaining the same number of spherical harmonics and triangular truncation. (The term "cubic" is due to the ability of the grid to represent cubic products in the dynamical equations.) In addition, the reduction of grid points along latitude circles as one approaches the poles is achieved using a triangular to octahedral mapping which corresponds to a poleward reduction of four points per latitude circle and an optimization of the total number of grid points and their local mesh resolution. ECMWF has documented superior filtering properties at higher resolution, an improved representation of orography, improved global mass conservation properties, substantial efficiency gains, and more scalable locally compact computations of derivatives and other properties that depend on nearest-neighbor information only. More details may be found in the publications cited below. NCAR's DECS is performing and supplying a grid transformed version of HRES IFS, in which variables originally represented as spectral coefficients or archived on a reduced Gaussian grid are transformed to a regular 5120 longitude by 2560 latitude N1280 Gaussian grid. In addition, DECS is also computing horizontal winds (u-component, v-component) from spectral vorticity and divergence where these are available.
