**3.3 Opportunities for providing climate information**

The selection of the types of adaptation that can be carried out in various regions is basically a follow-up to the National Action Plan - Climate Change Adaptation (RAN-API). Understanding the impacts of climate change varies depending on location or region. In this condition, an assessment of the impacts and vulnerability of climate change specific to the economic sector in a location or region is required as a first step in selecting climate change adaptation options. Furthermore, an evaluation of adaptation options is carried out considering that the implementation of climate change adaptation requires additional costs [19]. One of the important elements needed in conducting a climate change impact and vulnerability assessment is climate information. This climate information plays a vital role in identifying the impact of global climate change on climate conditions in a region. The trend of climatic elements such as rainfall and air temperature observations is the earliest stage to see the effects of climate change in an area. Climate information is needed to (1) undergo impact models, for example: crop simulation models to assess the impact of climate variability in a region on the agricultural sector, (2) validate climate model outputs for projecting future climate conditions, compiling climate change scenarios. The uncertainty of future climate change is often approached by using more than one climate model or emission scenario. To understand the capabilities of climate models, validation of climate model outputs for the current period (control) is carried out using observational climate information. Compiling climate change scenarios also requires observational climate information, for example by changing (adjusting) observational climate information with differences between future climate projections and control periods [20].
