Baltimore MD HydroNEXRAD (KLW) radar rainfall data set

The dataset consists of annual tar files (2000-2015) of radar rainfall for
the Baltimore Metropolitan Area. The data are processed from the Sterling
VA WSR88D radar (KLWX) using the HrdroNEXRAD Processing System. The area
covers a latitude range of 38.66 - 39.83 and longitude range of -77.4 to
-76.0 (approximately 100km x 100km) with a 1 sqkm grid size. The time step
is 15 minute, units are mm/ha. The years 200-2009 are bias corrected (see

Krajewski, Analyses of a long-term high-resolution radar rainfall data set
for the Baltimore metropolitan region, Water Resources Research, 48,
W04504, doi:10.1029/2011WR010641, 2012, for details) The time period 2010
- 2015 are not bias corrected. WE are including a bias value file
(Bias_Value_20102015.txt). The format of this file ' YYYY MM DD
ntimes biasvalue' where ntimes = number of 15 minute time periods
(max=96) available for the bias computation. The biasvalue info is as
follows: Total number of raingages for any time period is 54. If the bias
value > 3, then we set it 3. I fewer than 5 positive gage - radar pairs
(daily accumulation), set the bias to 1. If there are fewer than 80 (out
of 96) 15-minute radar fields for a day, set the bias to 1. A day is
selected from 12UTC to 12UTC, for example, the bias for 4/11/2011 means
12:00UTC 4/10/2011 to 12:00UTC 4/11/2011.
