Climate Explorer
This website provides access to relevant climate data focused on essential climate variables, based on NOAA Global Historical Climatology Nnetwork monthly (GHCNm), NOAA Global Historical Climatology Network hourly (GHCNh), DWD OpenData (Germany), and long-term homogenized Romanian datasets (RoCliHom).
GHCNh – Hourly Climate Observations
GHCNh dataset provides hourly observations from a global network of stations, enabling analysis of sub-daily variability and extremes. The dashboard visualizes NOAA NCEI metadata for the GHCN Hourly archive: https://www.ncei.noaa.gov/access/metadata/landing-page/bin/iso?id=gov.noaa.ncdc:C01688.
GHCNm – Monthly Climate Summaries
GHCNm dataset offers monthly climate summaries compiled from numerous weather stations worldwide. The dataset was first created in the early 1990s, with methodology updates released in 1997, 2011, and the latest versions in 2018 for air temperature and 2024 of precipitation. The duration of record for each station varies, with some of the earliest data reaching back to the 18th century. While certain station records are historical and no longer receive updates, many are still active and provide timely updates that are valuable for climate monitoring. The current iteration, GHCNm v4, includes average monthly temperature data and a beta version of monthly precipitation data. The current visualization, updated on November 30, 2025, includes only air‑temperature data.
DWD – German Climate Data
DWD section provides access to the Deutscher Wetterdienst (DWD) OpenData portal, offering comprehensive meteorological observations from Germany. This includes high-quality measurements of air temperature, precipitation, wind, and solar radiation.
RoCliHom – Romanian Homogenized Data
RoCliHom dataset includes homogenized monthly mean (Tavg), maximum (Tmax), and minimum (Tmin) air temperatures and precipitation (PREC) data from 156 weather stations covering 1901- 2023 period.
What You Can Do
Our goal is to make this vital data accessible and understandable, empowering individuals, researchers, and decision-makers alike to:
- Track historical trends: Explore long-term changes in precipitation and temperature to identify regional and global climate patterns.
- Analyze current conditions: Access up-to-date measurements to monitor current weather events and their potential impacts.
- Investigate climate variability: Delve into the fluctuations and extremes of precipitation and temperature to better understand climate risks.
By providing easy access to this essential climate data, we hope to contribute to a greater understanding of our planet’s climate system and support informed decision-making for a more sustainable future.
