http://iridl.ldeo.columbia.edu/ IRI/LDEO Climate Data Library
The IRI/LDEO Climate Data Library contains over 300 datasets from a variety of earth science disciplines and climate-related topics. It is a powerful tool that offers the following capabilities at no cost to the user: - access any number of datasets;
- create analyses of data ranging from simple averaging to more advanced EOF analyses using the Ingrid Data Analysis Language;
- monitor present climate conditions with maps and analyses in the Maproom;
- create visual representations of data, including animations;
- download data in a variety of commonly-used formats, including GIS-compatible formats.

CPC Unified Gauge-Based Analysis of Global Daily Precipitation
The Climate Prediction Center (CPC) Unified Gauge-Based Analysis of Global Daily Precipitation is an optimal interpolation objective analysis of global daily station precipitation data available at the CPC. It is divided into a retrospective version (RETRO) covering 1979 to 2005, derived from more than 30,000 gauges, and a real-time version (REALTIME) covering 2006 to present, derived from approximately 17,000 gauges. The grid resolution is 0.5 deg. lat/lon. The data set also includes information on the gauge network density and country-to-country variations in the daily reporting period.

NOAA NCEP EMC CFSv2
Climate Forecast System Version2 is now available as both hindcasts and realtime updates. 9-month hindcasts initiated from every 5th day and run from all 4 cycles of that day, beginning from Jan 1 of each year, over a 29 year period from 1982-2010. These hindcasts are available either as monthly sets of 24-28 ensemble members (ENSEMBLE), or starts every 5 days of four ensemble members (MONTHLY). Realtime updates are daily starts of four ensemble members (MONTHLY_REALTIME).

PRISM Temperature and Precipitation Analysis
The OSU PRISM (Parameter-elevation Regressions on Independent Slopes Model) Analysis of United States Precipitation and Temperature has been updated through Dec 2010, and will be automatically updated each month in the future. PRISM is a knowledge-based system that uses point measurements of precipitation, temperature, and other climatic factors to produce continuous, digital grid estimates of monthly, yearly, and event-based climatic parameters.

World Ocean Atlas 2009 (WOA09)
World Ocean Atlas 2009 (WOA09), from the U. S. National Oceanographic Data Center, is a set of objectively analyzed (1 degree latitude/longitude grid) climatological fields of in situ temperature, salinity, dissolved oxygen, Apparent Oxygen Utilization (AOU), percent oxygen saturation, phosphate, silicate, and nitrate at standard depth levels for annual, seasonal, and monthly compositing periods for the World Ocean. It also includes associated statistical fields of observed oceanographic profile data interpolated to standard depth levels on both 1 degee and 5 degree latitude/longitude grids .

NOAA ESRL 20th Century Reanalysis Version 2 (extended)
NOAA ESRL 20th Century Reanalysis Version 2 six-hourly data for 1871-2008. The analysis is performed with the Ensemble Filter as described in Compo et al. (2006) based on the method of Whitaker and Hamill (2002). Observations of surface pressure and sea level pressure from the International Surface Pressure Databank station component version 2 (Gleason et al. 2008), ICOADS (Woodruff et al. 2009), and the International Best Track Archive for Climatic Stewardship (IBTrACS, Kruk et al. 2010) were assimilated every six hours.
The IRI Server now has a local copy of all the mean fields; the IRI copy of the spread will be extended as needed. This should address some of the performance problems we were having.

TRMM_3B42 Precipitation Estimates
The combined instrument rain calibration algorithm (3B-42) uses an optimal combination of 2B-31, 2A-12, SSMI, AMSR and AMSU precipitation estimates (referred to as HQ), to adjust IR estimates from geostationary IR observations. Near-global estimates are made by calibrating the IR brightness temperatures to the HQ estimates.

average now has a /keepgrids option
The average operator normally removes each independent variable that is averaged over, so that, for example, a mean can easily be removed from an entire time series. But there is now a /keepgrids option, which keeps the independent variable as a single point grid. This is most useful for downloading to software that insists on a time grid.
