2020 State of Climate Services
Between 1970 and 2019, 79% of disasters worldwide involved weather, water, and climate-related hazards. These disasters accounted for 56% of deaths and 75% of economic losses from disasters associated with natural hazards reported during that period. As climate change continues to threaten human lives, ecosystems and economies, risk information and early warning systems (EWS) are increasingly seen as key for reducing these impacts. The majority of countries, including 88% of least developed countries and small island states, that submitted their Nationally Determined Contributions (NDCs) to UN ...
Guidelines on Homogenization
This publication provides guidance on homogenization of instrumental land station data. For beginners, the publication describes prerequisites for homogenization (including data rescue, quality control, metadata, parallel measurements etc), explains homogenization practices in detail and provides an overview of homogenization software packages. For advanced users, the history and mathematical theory of homogenization is introduced.

Capacity Development for Climate Services: Guidelines for National Meteorological and Hydrological Servi
These guidelines are intended to provide National Meteorological and Hydrological Services (NMHSs) and other climate service providers with up-to-date information on available resources, strategies, procedures and best practices to help develop their capacities in the provision and use of climate services at the global, regional and national level. The guidance focuses on enhancing the capacity of NMHSs in four key areas: institutional, infrastructural, procedural and human resources. These four areas must be considered together to achieve sustainable capacity development.
