The result is NASA's Integrated Multi-satellite Retrievals for GPM data product, called IMERG, which combines all of these data from 12 satellites into a single, seamless map. The role of extreme rain events in Peninsular Florida’s seasonal hydroclimate variations. There is a greater discrepancy in precipitation estimates in the northwest regions of China, and over the Tibetan Plateau (Ma et al., 2009; Miao et al., 2015; Sun, Miao, et al., 2014). Furthermore, tropical precipitation is characterized by high spatiotemporal variability and stems mainly from convective events, which requires accurate parameterization schemes and high resolution in the reanalysis model (Pfeifroth et al., 2013). Reanalysis data sets had a larger degree of variability than the other types of data sets. The seasonal contributions to the difference in annual precipitation are slightly larger for JJA and MAM than for the other seasons. PRECL data include measurements from over 17,000 stations in the GHCN2 and the Climate Anomaly Monitoring System data sets. Several gridded precipitation data sets based entirely on gauge information have been constructed and are in wide use (summarized in Table 1). and Paleomagnetism, History of There are several sources for downloading and viewing data which allow you to subset the data to only include specific parameters and/or geographic locations. This reduction may be due to increasing operational and staffing costs associated with ground‐based data collection, restrictions on the release of the data by NMAs, migration and abandonment of sites, and economic and political factors (Strangeways, 2006). When compared with station data for extreme precipitation, the NCEP products (especially NCEP2) fare better than the ECMWF products, which can be attributed to the differences in model parameterizations, spatial resolution, and input data assimilation (Zolina et al., 2004). Estimation of the Atmospheric Ice Content Mass, Spatial Distribution, and Long‐Term Changes Based on the ERA5 Reanalysis. Sensors onboard satellites are currently the only instruments that can provide global, homogeneous, precipitation measurements. However, differences in extreme precipitation estimates are lower at higher latitudes than at lower latitudes, which is not consistent with the results for mean precipitation estimates. Climate Change and Social Unrest: A 6,000‐Year Chronicle From the Eastern Mediterranean. The difference in precipitation estimations at each grid location is represented by the range between the 75th and the 25th percentile. There were slightly greater discrepancies associated with estimates of extreme precipitation events at lower latitudes than at higher latitudes, which is inconsistent with the results for mean values. If you do not receive an email within 10 minutes, your email address may not be registered, Therefore, the number of stations utilized for GPCC Climatology is exactly 67,298 stations for the best covered month (June) and exactly 67,149 stations for the worst covered month (December).

Moreover, the number of gauges in use is growing smaller (Figure 2). Evaluation of reanalysis and global meteorological products in Beas river basin of North-Western Himalaya. In March‐April‐May (MAM), September‐ October‐ November (SON), and December‐January‐February (DJF), the CFSR estimates exceed those of the other products. NMAs provide the primary data for the GPCC, with 158 countries and 31 regional suppliers providing the majority of the gauge data in the GPCC database. At any given time, instruments onboard about a dozen satellites contribute to a record of the world’s rain and snow. (a–d) Distributions of rain gauges used for July 2005 in the data sets CPC, GPCC, CRU, and PRECL, respectively. Variable number of stations per grid over time can be a major inhomogeneity source. In tropical regions, discrepancies between products did not increase when satellite estimates were included (Figure 9). (Figure produced via "GPCC Visualizer" tool), GPCC percent [%] of normal for May 2012. Data, 5, 71-99. For instance, the Global Precipitation Climatology Project (GPCP) monthly precipitation analysis merges gauge observations with low‐orbit‐satellite MW data and geosynchronous‐orbit‐satellite IR data and is one of most popular products used in climate studies (Adler et al., 2003). Evaluation of bias correction methods for APHRODITE data to improve hydrologic simulation in a large Himalayan basin. To meet the need for a high‐quality, observation‐based, large‐scale precipitation data set covering both land and ocean for the period before the 1970s, the U.S. CPC has constructed a monthly precipitation data set beginning in 1948. Imputation of missing sub-hourly precipitation data in a large sensor network: a machine learning approach. Journal of Geomagnetism and Aeronomy, Nonlinear The algorithm for obtaining instantaneous precipitation in the GPCP 1dd uses the Threshold Matched Precipitation Index (TMPI) for 40°N–40°S, based on a merged geo‐IR data set from IR brightness temperatures, and rescaled TOVS precipitation estimates at higher latitudes (Huffman et al., 2001). Reliability and discrepancies of rainfall and temperatures from remote sensing and Brazilian ground weather stations. Knowledge of the drop‐size distribution is essential for understanding precipitation processes, estimating rainfall, and improving microphysics parameterizations in numerical cloud models. Termed the precipitation reconstruction (PREC), this global analysis is constructed by interpolating gauge observations over land (PRECL) and by empirical‐orthogonal‐function reconstruction of historical observations over ocean (Chen et al., 2002). Acquiring unbiased rainfall duration and intensity data from tipping-bucket rain gauges: A new approach using synchronised acoustic recordings. PPDIST, global 0.1° daily and 3-hourly precipitation probability distribution climatologies for 1979–2018. CFSR reproduces both the regional pattern and the local details for the precipitation mean and variability fairly well, because it has the finest resolution of all data sets and includes coupled ocean‐atmosphere assimilation in the models (Zhang et al., 2012).
