Abstract

<p>The monthly means of NCEP/NCAR Reanalysis (R1) products, archived in <a href="http://rda.ucar.edu/datasets/ds090.0/">ds090.0</a> 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). </p> <p>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 <a href="http://rda.ucar.edu/datasets/ds090.2/docs/how2use_grads.txt">this guide</a>. </p> <p>All subgroups will be available on line under <a href="http://rda.ucar.edu/datasets/ds090.2/#access">data</a>. The ones that are not on line yet will be moved over upon request. </p>
