This dataset is a compilation of in situ daily meteorological observations for Kazakhstan within the framework of joint efforts to create Global Daily Climatology Network (GDCN) among the Kazakhstani Scientific Research Institute of Ecology and Climate of the Ministry of Environment Protection of the Republic of Kazakhstan, All-Russian Research Institute for Hydrometeorological Information-World Data Center of the Federal Service for Hydrometeorology and Environmental Monitoring, Obninsk, Russian Federation, and NOAA National Climatic Data Center, Asheville, North Carolina.

**Version 1 of the dataset has been superseded by a newer version. Users should not use version 1 except in rare cases (e.g., when reproducing previous studies that used version 1).** The International Best Track Archive for Climate Stewardship (IBTrACS) dataset was developed by The NOAA National Climatic Data Center, which took the initial step of synthesizing and merging best track data from all official Tropical Cyclone Warning Centers (TCWCs) and the WMO Regional Specialized Meteorological Centers (RSMCs) who are responsible for developing and archiving best track data worldwide.

The US Environmental Protection Agency - Western Ecology Division (EPA) has been monitoring above- and belowground climate data from 23 locations along an Oregon Cascade Mountain Crest-to-Coast transect since 1993. The start date for the sites varied over a several year period. The monitoring sites were located in old-growth and non old-growth coniferous forests (douglas fir, sitka spruce, alder, juniper, ponderosa pine), adjacent clear-cuts, and top of canopy locations.

The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview - Global Snow & Ice report provides a global view of snow and ice, placing the data into a historical perspective. Because the Northern Hemisphere has the vast majority of the planet's seasonal snow cover, the report focuses on the Northern Hemisphere snow cover extent. In addition to snow cover, sea ice extents in both hemispheres are included.

The NCEP Climate Forecast System Reanalysis (CFSR) was designed and executed as a global, high resolution, coupled atmosphere-ocean-land surface-sea ice system to provide the best estimate of the state of these coupled domains over the 31-year period of 1979 to 2009. A complete Reforecast of CFS version 2, over the 30-year period (1981-2011) has been created in order to provide stable calibration and skill estimates of the new system, for operational seasonal and sub seasonal prediction at NCEP.

The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview - Hurricanes & Tropical Storms report focuses primarily on storms and conditions that affect the U.S. and its territories, in Atlantic and Pacific basins. The report places each basin's tropical cyclone activity in a climate-scale context. Key statistics (dates, strengths, landfall, energy, etc.) for major cyclone activity in other basins is occasionally presented. Reports began in June 2002.

The AEWC dataset was created using a new algorithm developed by researchers at Georgia Tech and represents the first attempt to produce a standard easterly wave tracking dataset for the East Pacific, Atlantic, and Africa. The algorithm uses curvature vorticity anomalies to identify the location of easterly waves as a function of time. The dataset provides 6-hourly coverage over a 63-year period (January 1948-December 2010) in the region bounded by 35S-35N x 140W-40E.

This dataset contains Level 1c inter-calibrated brightness temperatures from the Microwave Sounding Unit (MSU) sensors onboard nine polar orbiting satellites (TIROS-N, NOAA-6, -7, -8, -9, -10, -11, -12, and -14) spanning from 1978 to 2006. The dataset was produced by the NOAA Center for Satellite Applications and Research (STAR), and is a Fundamental Climate Data Record (FCDR) of microwave brightness temperatures in the NOAA CDR Program.

This dataset contains Level 1c inter-calibrated brightness temperatures from the Advanced Microwave Sounding Unit-A (AMSU-A) sensors onboard six polar orbiting satellites (NOAA-15, -16, -17, -18, EUMETSAT MetOp-A, and NASA Aqua) spanning from 1998 to the present. The dataset was produced by the NOAA Center for Satellite Applications and Research (STAR), and is a Fundamental Climate Data Record (FCDR) of microwave brightness temperature in the NOAA CDR Program. AMSU-A is a 15-channel microwave radiometer with a ground spatial resolution of about 50 km in diameter at nadir.

The Special Sensor Microwave Imager/Sounder (SSMIS) is a series of passive microwave conically scanning imagers and sounders onboard the DMSP satellites beginning with F-16. SSMIS improves upon the surface and atmospheric retrievals of the previous Special Sensor Microwave Imager (SSM/I), and upon the atmospheric temperature and water vapor sounding capabilities of both the Special Sensor Microwave Temperature Sounder (SSM/T-1) and the Special Sensor Microwave Humidity Sounder (SSM/T-2).
