A curated registry of the GLASS product archive (glass.hku.hk/archive/),
one row per archive variant (product x source x resolution). It stores the
archive URL layout, the observed year coverage, and—for the variants whose
sample files have been checked—file-name fragments and band scaling
metadata used by glass_read().
Usage
data(glass_products)Format
A tibble with one row per archive variant:
- product
Product directory under /archive/, e.g. "LAI"
- long_name
Human-readable product name
- variant_id
Unique key, e.g. "LAI_MODIS_250M"
- source
Source/series sub-directory, e.g. "MODIS", "AVHRR"
- res
Resolution sub-directory, e.g. "250M";
NAif absent- layout
Archive layout: "year_doy" (year/composite folders), "flat" (static file collection), "year_files" (granules directly under year folders, e.g. AVHRR CMG) or "year_yyyddd" (daily YYYYDDD folders, e.g. AWGF LST)
- observed_years
Year coverage observed in the directory tree, e.g. "2000-2025"
- start_year, end_year
First/last observed year,
NAif unobserved- cadence_days
Days per synthesis cycle, e.g. 8 for the 8-day products
- temporal_res
Temporal resolution label, e.g. "8 days", "daily"
- version
Product version fragment of the file names, e.g. "V60"
- code
GLASS dataset code fragment, e.g. "GLASS01D01"
- layer
Layer name suffix in file names, e.g. "LAI";
NAwhen files carry no suffix- fill_value
Fill value of the raw storage, e.g. 255
- scale_factor
Scale factor applied to raw values, e.g. 0.01
- valid_min, valid_max
Valid data range after scaling
- verified
TRUEfor variants where naming and band metadata were validated against a real granule- url_root
Base URL of the variant, i.e. /archive/product/source/res/
