Operational Data Services
National Meteorological and Hydrological Services (NMHSs) in the Pacific Islands region operate and maintain their own climate observation networks. Climate data are quality checked and stored in national climate databases. The data resources below can be used to compare with national climate datasets and to assess regional trends and patterns.
Regional and Global Climate Data
The Pacific Climate Change Data Portal provides historical climate information and trends from individual observation sites across the Pacific region and East Timor.
The Global Historical Climatology Network-Monthly (GHCN-M) temperature dataset was first developed in the early 1990s. A second version was released in 1997. The latest iteration was released in May of 2011.
The Integrated Surface Database (ISD) consists of global hourly and synoptic observations compiled from numerous sources into a single common ASCII format and common data model.
Tropical Cyclone Data
The Southern Hemisphere Tropical Cyclone Data Portal improves knowledge of past tropical cyclone activity in the Pacific Islands and Timor-Leste by plotting tracks of cyclones in the South Pacific from 1969. Meteorologists and stakeholders can use this tool to analyse the tracks of historical tropical cyclones and relate them to the impact on lives and infrastructure recorded on the ground.
Sea Level Data
The Climate and Oceans Support Program in the Pacific (COSPPac) Ocean Portal: Sea Level page is a tool for plotting and downloading historical sea level data from tide gauges from across the Pacific Islands region and from satellite altimetry.
The UHSLC tide gauge data has two levels of quality-control (QC): Fast Delivery (FD) data are released within 1-2 months of data collection and receive only basic QC focused on large level shifts and obvious outliers; and Research Quality Data (RQD) receive thorough QC and are considered to be the final science-ready data set. This final QC process is time-consuming, and as a result, the RQD are released 1-2 years after data is received from the data originators.
Multiple oceanic and atmospheric global datasets provided by Asia-Pacific Data Research Center, which is a part of the International Pacific Research Center at the University of Hawaiʻi at Mānoa.
Data Management Services
CliDE (Climate Data for the Environment) is a Climate Data Management System (CDMS) which provides Pacific Island countries with a central database for climate records, with key entry forms, quality assurance tools, reports and data dumps. It is free and open-source software, using a web-based user interface and high reliability relational database system.
Tideda (Time Dependent Data) is a software package for making databases to store and analyse any time series data. It is particularly suitable for processing environmental and hydrological data.
