2000-2015: Monthly Means of Daily Means Wind Speed TIFFs for the Lake Victoria Region

2000-2015: Monthly Means of Daily Means Wind Speed TIFFs for the Lake Victoria Region Reference System: SR-ORG:14 Developed for: NSF Award Number: 1518532 CNH-L: The Potential for Aquaculture in Lake Victoria and Implications for Wild Fisheries and Fish Commodity Markets File Naming Convention: All TIFFs are named under the following naming convention: YYYY_MMWS, where YYYY refers to year of the data, MM refers to the month, and WS refers to Wind Speed. This wind speed data set was developed for the purposes of National Science Foundation (NSF) Coupled Natural and Human systems research. Data Origin: Original dataset was downloaded from: http://apps.ecmwf.int/datasets/data/interim-full-moda/levtype=sfc/ Original data downloaded was ERA Interim, Monthly Means of Daily Means, and was developed by the European Centre for Medium-Range Weather Forecasts (ECMWF). Data was downloaded as single component 10 meter Wind Speed data packaged as NetCDF. Data values are measured in m/s-1. Data values are monthly means of daily means. Data is representative of surface level collection. Origin data was derived and developed from reanalysis. ECMWF, the data provider and developer, defines their methods of reanalysis as follows: “Reanalysis (as well as analysis) is a process by which model information and observations of many different sorts are combined in an optimal way to produce a consistent, global best estimate of the various atmospheric, wave and oceanographic parameters.” http://www.ecmwf.int/en/how-are-data-obtained-do-they-come-observations-or-have-they-been-derived-numerical-models Extent downloaded: (degrees) N: 2 W: 27 S: -5 E: 36 Resolution downloaded: (degrees) 0.125 x 0.125 (approx. 14km at the equator). Data Development/Processing: These data were downloaded individually as monthly 10 meter Wind Speed in NetCDF format then converted to TIFF using the following GDAL script. for %A in (\"C:\temp\*.nc\") do gdal_translate -of GTiff -ot FLOAT32 -a_srs \"+init=epsg:4326\" -unscale -co \"COMPRESS=PACKBITS\" \"%A\" \"%A.tif Converted TIFF data was validated against the parent NetCDF file for correct cell size and pixel value.
