|September 2, 2025
Summary
A new daily rainfall grid dataset for West Java (1991-2020) was created using 162 rain gauges. This high-resolution spatial rainfall data aids climate analysis and water resource management.
Area of Science:
- Climatology
- Hydrology
- Geospatial Analysis
Background:
- Accurate rainfall data is crucial for climate analysis and water resource management.
- Spatial distribution of local-scale rainfall data presents a significant research challenge.
- Finer resolution rainfall data is essential for climate change adaptation and water planning.
Purpose of the Study:
- To establish a daily, high-resolution gridded dataset of observed rainfall for West Java, Indonesia.
- To provide a foundation for improved climate analysis and water resource management in the region.
- To support adaptation strategies for hydro-meteorological hazards.
Main Methods:
- Utilized daily rainfall data from 162 rain gauges monitored by the Indonesian Agency for Meteorology Climatology and Geophysics (BMKG) from 1991-2020.
- Employed the Inverse Distance Weighting (IDW) approach for spatial interpolation.
- Generated daily, monthly, and annual rainfall time-series at a 0.05° grid resolution.
Main Results:
- A comprehensive daily gridded rainfall dataset for West Java was successfully established.
- The dataset covers a 30-year period (1991-2020) with daily, monthly, and annual resolutions.
- The spatial interpolation effectively captured rainfall variations across diverse terrains and climate zones.
Conclusions:
- The developed gridded rainfall dataset provides a valuable resource for local climate studies in West Java.
- This data is instrumental for effective water resource planning and management.
- It serves as a critical tool for developing adaptation strategies against hydro-meteorological risks.

2.0K
Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...

Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate. Ideally, the concentration of the precipitating reagent should be low with effective stirring to maintain low relative supersaturation for the growth of large crystals. In homogeneous precipitation, the precipitant is slowly generated by a chemical reaction in the solution to avoid local reagent excesses. For example, urea decomposes gradually to...

Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...
