Use of H SAF Products in projects


The H-SAF products are primarily utilized in the context of fulfilling the statutory obligations of the Institute of Meteorology and Water Management - National Research Institute (IMGW-PIB), pertaining to the meteorological and hydrological protection of the country, which are regulated by appropriate laws and ordinances. These products are exclusively accessible through internal services and serve as a tool for synoptists in their operational work ( This applies to soil moisture (H14, H26), precipitation (H60B, H61B), and snow products (H10).

Visualizations and processing results of some products are publicly available through dedicated web services, maintained by IMGW-PIB, utilized by other organizations and institutions: agrometeorological service - visualization of H26 products (, and charts of average soil moisture progression in administrative units ( Based on satellite data, monthly agrometeorological bulletins are also developed (

A key project in which soil moisture products are employed is "stopsuszy" ("stopdrought"): IMGW-PIB provides information concerning current hydrological and meteorological conditions in terms of drought monitoring: - including soil moisture ( The project utilizes a portion of data published in the agrometeorological service of IMGW-PIB.

Climate Change Initiative (CCI)https://www.esa-soilmoisture-cci.orgThe Soil Moisture CCI project is part of the ESA Programme on Global Monitoring of Essential Climate Variables (ECV), better known as the Climate Change Initiative (CCI), initiated in 2010 and producing an updated soil moisture product every year. CCI Soil Moisture produces
  • annually algorithmically updated global climate data record of soil moisture spanning over 40 years
  • 3 separate soil moisture products derived from active, passive and combined (active + passive) sensors and a break-adjusted product based on combined
  • 13 public releases to date, each updated with new sensors and extended time series
