*Show Figure Label: If the visualization is referred to in the text of the report and needs a figure number (i.e. Learn more about writing alt text for FEWS NET visualizations. *Alt Text: Provide a brief description of what the visualization shows. You may use it to help you quickly identify a specific visualization in your report in the CMS. Internal Title: This field is optional and will not show up in the report. * = typically required for reports Standard Visualization Fields Use the following guidelines to create a Remote Sensing Map. Note: The pop-up time series chart shown below is only available for country and region-level Remote Sensing Maps. This visualization is normally used for Seasonal Monitors, Weather Hazards reports, and Food Security Outlook reports as required. The regional or country specific graphics show individual days for the first 6 of the 7-day forecasts, and are displayed in conjunction with the past 6 days of rainfall estimates.The Remote Sensing Map is a map with remote sensing data from the USGS GeoEngine API. The global extent graphics are for the 1st day of the 7-day period and for the total 7-day accumulation. Graphic images are provided for both global and regional extents from the original data. More information on the GFS data can be found at. These data are 7 day forecasts of precipitation at 0.25 degree resolution with a global extent. The Global Forecast System (GFS) precipitation data are provided on a daily basis by the Africa desk of the NOAA Climate Prediction Center ( ). The daily data are provided for download in three formats: daily, monthly daily data (~2MB per month), and annual daily data (~25 MB per year). In the case of Africa, the entire collection is available through the FEWS NET Bulk RFE Data Download page at Africa/Dekadal RFE.The individual daily RFE images are ~65-80 KB per file. Each daily rainfall file is a UNIX *.tar.gz file which contains the ArcInfo *.bil image and related files (i.e.bil. The naming convention for the daily image zip file is rain_ where YYYY is the 4 digit year and JDA is the 1-to-3 digit day of the year. The Central Asia window data are under the afghan sub-directory, and the South Asia window data are under the seasia sub-directory. The Africa window data are under the africa sub-directory. All data remain on this server for 8 days before being auto-deleted. Data for Afghanistan, Iraq, Yemen, and the 4-country region of Kyrgyzstan, Tajikistan, Afghanistan, and Pakistan are all extracted from the Central Asia window.Īll data are in geographic coordinates at 0.10 degree resolution.Įach region's daily data are downloaded from NOAA/CPC and converted into ArcInfo integer (to the nearest whole millimeter) *.bil images which are then zipped and staged at. The graphic below illustrates the 3 windows of the RFE 2.0 daily data. The windows and their bounding coordinates are: The RFE 2.0 daily (06Z to 06Z) data are compiled over three geographic areas or windows for the FEWS NET project. This algorithm replaced the dekadal (or 10-day) version 1.0 that was operational from 1995 through 2000 ( Herman et al., 1997).Ī detailed description of the NOAA CPC daily RFE 2.0 data can be found at the bottom of the web page Product Documentation NOAA Daily RFE 2.0 DataĪs of January 1, 2001, RFE version 2.0 was implemented by the NOAA Climate Prediction Center (CPC).
