  • The Joint IPWG/GEWEX Precipitation Assessment 
    Roca, Rémy; Haddad, Ziad S.; Akimoto, Fumie F.; Alexander, Lisa; Behrangi, Ali; Huffman, George; Kato, Seiji; Kidd, Chris; Kirstetter, Pierre-Emmanuel; Kubota, Takuji; Kummerow, Chris; L’Ecuyer, Tristan; Levizzani, Vincenzo; Maggioni, Viviana; Massari, Christian; Masunaga, Hirohiko; Schröder, Marc; Tapiador, Francisco J.; Turk, Francis J.; Utsumi, Nobuyuki (World Climate Research Programme, 2021)
    This report reviews the current state of precipitation products, and includes assessments of sub-daily global satellite precipitation products, discussions of various climate applications of precipitation products, and ...
  • Intrinsic uncertainty in the sub-daily satellite products at their native resolutions 
    Haddad, Ziad S.; Turk, Francis J.; Utsumi, Nobuyuki; Kirstetter, Pierre-Emmanuel (World Climate Research Programme, 2021)
    Level-3 “sub-daily global merged satellite precipitation products” are typically reported on a fixed rectangular latitude-longitude grid at high spatial and temporal resolution (respectively 0.1º and ~0.5 hour). This section ...
  • Toward the new generation of products 
    Huffman, George; Kirstetter, Pierre-Emmanuel (World Climate Research Programme, 2021)
    Modern precipitation products provide fine resolution precipitation estimates by combining estimates from many individual high-quality satellite sensors and by using approximations to fill numerous gaps in the mosaics of ...
  • Intercomparison of products for climate applications 
    Masunaga, Hirohiko; Akimoto, Fumie F.; Kubota, Takuji; Kummerow, Chris; Schröder, Marc (World Climate Research Programme, 2021)
    Observational datasets of global precipitation are widely used for a range of climate applications. The precipitation products, however, are not strictly a “true” representation of nature, but have their own uncertainties ...
  • List of Acronyms 
    Unknown author (World Climate Research Programme, 2021)
    This list contains the acronyms used in The Joint IPWG/GEWEX Precipitation Analysis along with their definitions.
  • Emerging techniques for precipitation assessment and consistency studies 
    Behrangi, Ali (World Climate Research Programme, 2021)
    Besides traditional sensors used to estimate precipitation amount and distribution, several other Earth-observing sensors can provide valuable insights about precipitation quantity. Here, we show how observation of mass ...
  • Directions in error modeling 
    Maggioni, Viviana; Massari, Christian (World Climate Research Programme, 2021)
    Although in the recent past numerous attempts have been made to develop error models of satellite precipitation products, several issues limit their use in applications. First off, the majority of these approaches is based ...
  • Climate model validation 
    Tapiador, Francisco; Levizzani, Vincenzo (World Climate Research Programme, 2021)
    This chapter reviews the use of satellite-derived precipitation datasets to validate climate models, with an emphasis in quality control and normalization. Two checklists are provided: one with the facts regarding the major ...
  • Validating the intrinsic uncertainty: Implications for hydrologic applications 
    Kirstetter, Pierre-Emmanuel (World Climate Research Programme, 2021)
    The critical importance of accurate water flux estimates for science and applications explains the large body of verification analyses focusing on precipitation estimates. Very few are implemented at the relevant scales ...
  • Extreme and intense precipitation 
    Roca, Rémy; Masunaga, Hirohiko; Alexander, Lisa (World Climate Research Programme, 2021)
    The availability of numerous gridded precipitation products and the importance of the question of extreme precipitation have led to a number of new findings. Over land, this intercomparison generally emphasizes that global ...
  • Energy and water closure 
    Roca, Rémy; Kato, Seiji; L’Ecuyer, Tristan (World Climate Research Programme, 2021)
    Energy and water budget closure has recently been extensively used to assess the consistency of precipitation products with various other terms of the water and energy budget. Most efforts are focused on water closure and ...
  • Climate variability and trends 
    Tapiador, Francisco J. (World Climate Research Programme, 2021)
    This chapter describes the role of satellite precipitation datasets in the analysis of climate variability and trends. Two major applications are explored, namely the validation of the variability in the statistical moments ...
  • Monitoring of satellite precipitation estimates through the IPWG validation studies 
    Kidd, Chris; Maggioni, Viviana (World Climate Research Programme, 2021)
    A major activity of the International Precipitation Working Group (IPWG) is the verification, validation and intercomparison of precipitation products to enable product developers and users to continually monitor and assess ...
  • Requirements for a constellation of precipitation sensors 
    Kidd, Chris (World Climate Research Programme, 2021)
    Satellites within the current precipitation constellation are old, with many missions beyond their designed operational lifetime. It is therefore crucial that there is a concerted program of new satellites and sensors to ...
