land4health 0.3.1

• The documentation and package URL have been corrected when land4health starts up upon loading the package.
• Added the Wellcome funding badge to the pkgdown website (_pkgdown.yml).
• Authors@R in DESCRIPTION was updated to include the new contributor, with their role (aut) and ORCID identifier.

land4health 0.3.0 (2026-10-08)

• l4h_era5land() gains support for ERA5-Land climate variables ("t2m", "d2m", "pr", "soil", "pet") at daily or monthly.

• l4h_surface_temp() gains a by argument ("day"/"month") to extract LST values at daily or monthly resolution. When by = "month", cloud-masked pixels are excluded before the temporal reduction, so low-quality observations do not bias the monthly summary. The "day" option remains the default, so existing code is unaffected.

1. Vector-borne disease

• ✔ add l4h_malaria(), this function extracts modeled malaria metrics (incidence rate, incidence count, parasite rate, mortality rate, mortality count) for Plasmodium falciparum and Plasmodium vivax from the Malaria Atlas Project GeoServer via WCS 2.0.1. Automatically selects the latest release available.

• ✔ add l4h_dengue() ,downloads dengue case counts from the OpenDengue Project, a harmonized, open-access repository of dengue surveillance data from national ministries of health. The function supports national, spatial, and temporal extracts filtered by WHO region and country for a specified date range.

2. Climate

• ✔ add l4h_chirps(), this function extracts precipitation values (daily, monthly, and annual) from CHIRPS v3. The user can choose between IMERG-based (product = "sat") or ERA5-based (product = "rnl") daily products.

• ✔ add l4h_surface_temp(),extracts daytime or nighttime Land Surface Temperature (LST) for a user-defined region and time range using the MODIS MOD11A1.061 product

3. Human intervention

• ✔ add l4h_night_lights(), extracts global night‑time lights using harmonized DMSP‑OLS and VIIRS data.

• ✔ add l4h_urban_rural_area(), calculates the surface area (in km2) of urban, rural, or all settlement classes every 5 years between 1985 and 2030 using the GHS-SMOD R2023A dataset.

• ✔ add l4h_human_built(), extracts built‑up surface area from GHSL Built‑Up Surface dataset.

4. Environment

• ✔ add l4h_co_column(), extracts carbon monoxide (CO) concentration from Sentinel-5P TROPOMI.

• ✔ add l4h_urban_heat_index(), calculates the Surface Urban Heat Island (SUHI) index using MODIS LST and GHS-SMOD.

5. Utils

• ✔ add l4h_ee_extract() like an alternative to some problems withee_extract

6. Others

• New badge to give credit to Innovalab .
• Reduction in the number of dependeces
• Improving the progress bar using only the cli package.

7. Removed

• Removed l4h_water_proportion(). The MapBiomas Peru water dataset does not yet have a stable API or consistent versioning for reliable programmatic access.
