Description Usage Arguments Value Note References See Also Examples

Download MIRCA2000 global data of monthly irrigated and rainfed crop areas around the year 2000 (MIRCA2000). See https://www.uni-frankfurt.de/45218023/MIRCA for more detailed information on these data.

1	get_mirca(cropname, rainfed = TRUE, plot = TRUE, cache = TRUE)

`cropname`	a MIRCA2000 crop name, see `df_mirca` for a full list. Fuzzy string matching via `base::agrep` is done.
`rainfed`	default=TRUE, FALSE for irrigated
`plot`	default=TRUE, plot the resulting raster
`cache`	default=FALSE, TRUE to save MIRCA2000 files locally for future use with `climcropr`

A raster object of MIRCA2000 crop data and optionally a gzipped file of the original data saved to local disk for future use with climcropr.

The data used in this package are downloaded from:

ftp://ftp.rz.uni-frankfurt.de/pub/uni-frankfurt/physische_geographie/hydrologie/public/data/MIRCA2000/harvested_area_grids/

The documentation for irrigated crops was published as Frankfurt Hydrology Paper 06:

Portmann, F., Siebert, S., Bauer, C. & Döll, P. (2008): Global data set of monthly growing areas of 26 irrigated crops. Frankfurt Hydrology Paper 06, Institute of Physical Geography, University of Frankfurt, Frankfurt am Main, Germany.

The documentation for both rainfed and irrigated crops is published in a peer-reviewed journal:

Portmann, F. T., Siebert, S. & Döll, P. (2010): MIRCA2000 – Global monthly irrigated and rainfed crop areas around the year 2000: A new high-resolution data set for agricultural and hydrological modeling, Global Biogeochemical Cycles, 24, GB 1011, doi:10.1029/2008GB003435.

For Frankfurt Hydrology Paper 09, the documentation for irrigated crops was updated especially with respect to data quality and scaling. Data quality parameters by country and unit, and crop calendars for rainfed and irrigated crops for each unit are now available, too:
