Webtools to plot/analyze data by Function

Data Extraction

1. NCDC NOMADS and NCMP:  reanalysis (CFSR,NARR,R1,R2); NWP (NAM, GFS, RUC); GENS ensembles, SST
2. NOAA/ESRL Search and Plot. (R1,R2,20CR, NARR)
3. IRI (CFSR,20CR,R1,R2)
4. ECMWF ERA-40, ERA-Interim (Get netCDF or GRIB files from the daily or subdaily data)
5. Goddard Earth Science Model Data Information Sevices Center (MERRA)
6. NCAR, Highest-resolution files for all reanalyses, except MERRA.  GRIB parameter field extraction using cURL, and some conversion to netCDF as noted. 
   1. JRA-25: Data Access > Internet Download > Create Your Own File List (e.g. anl_p), use cURL or wget (for files).
   2. ERA-Interim - same as JRA-25.
   3. CFSR - same as JRA-25 (also subset with net CDF format conversion)
   4. 20CR - same as JRA-25
7. MERRA Data Subsetter  (variable list and what file to look at for a particular variable)
8. openDAP servers: NOAA/ESRL (20CR,R1,R2,NARR), NCEP, MERRA2D, MERRA3D
9. OpenDAP: MERRA Gridded Innovations and Observations (GIO)
10. OpenGrADS.org: GrADS software with additional user functionality, including GUI for reanalyses including NCEP and MERRA

Basic Maps

1. IRI (CFSR,20CR,R1,R2)
2. ESRL/PSD Search and Plot (20CR,R1,R2,NARR)
3. Merra: Uses Giovanni to produce maps or animations of some monthly fields. Can average over successive times.
4. NOMADS (CFSR,NARR,R1,R2)
5. ECMWF ERA-40, ERA-Interim (Plot maps)
6. MERRA Atlas
7. MERRA Web App

Other Basic Geographic Plots

1. ESRL: Crossections
2. Search and Plot
3. Merra: Uses Giovanni to produce hovmollers of some monthly fields.
4. KMNI.

Hovmollers

1. ESRL/PSD: Hovmollers (R1)
2. IRI

Advanced Plots

1. ESRL/PSD: Can plot monthly, daily and sub-daily of crossections from composite plotting pages (R1). Anomalies are available.
2. ESRL/PSD: Hovmollers of means, anomalies of daily data. Anomalies are available (R1).

Composite Maps (Average different non contiguous dates together)

1. ESRL/PSD: Can plot composite maps and vertical crossectons from composite plotting pages on monthly, daily and sub-daily time scales for R1. Anomalies are available.
2. ESRL/PSD: Can plot composite maps from plotting pages on monthly, daily and sub-daily timescales for 20CR. Anomalies are available.
3. GCOS/WGSP: Can plot composite maps of sea level pressure from plotting pages on monthly timescales. Anomalies are available.

Correlation Maps

1. ESRL/PSD: From monthly NCEP/NCAR R1
2. KMNI

Timeseries Plots

1. NOMADS
2. TDS
3. NOAA/ESRL PSD: Plot simple timeseries of NCEP/NCAR R1 and 20thC Reanalysis monthly variables
4. IRI

Timeseries Analysis

1. KMNI: Plot, compute annual cycle, filter and other tools available for time series analysis. Provides many climate/ocean timeseries.
2. ESRL/PSD: Correlate and do some other simple analysis on pregenerated or user supplied monthly timeseries
3. ESRL/PSD: Extract daily timeseries from datasets. Can supply user criteria (e.g. top 10 temperatures in January for a point). R1,20CR
4. ESRL/PSD: Extract monthly timeseries from datasets.  R1,20CR
5. IRI

Google Earth
