RAIN GAUGE NETWORK OVER THE MESOSCALE OBSERVATORY OF THE Upper Oueme Hydrometeorological Observatory in Benin (OHHVO*) --------------------------------------------------------------------------------------------------------------------- * OHHVO : Observatoire Hydrométéorologique de la Haute Vallée de l'Ouémé. Location (Cf. map in Raingages_Network.BMP): -------------------------------------------- The catchment basin of the Upper Valley of Ouémé in Benin covers 14287 km² approximatly 1.5°E to 2.5°E 9°N to 10°N quadrangle. It includes the sub-catchment of the Donga (590km²) which constitutes the supersite for hydrological modelling. The rain gauge network (cf. list in Raingage.Stations.xls): ---------------------------------------------------------- - Number of stations : 55. - period of measurements : 2001-2003. - type of rain gauges : . OEDIPE : tipping bucket 0.5 mm increment . OEDIPE_P91 : tipping bucket 0.5 mm increment . OTT250 : weighting at 1 minute time step (maximum capacity of the backet 250 mm) . OTT1000 : weighting at 1 minute time step (maximum capacity of the backet 1000 mm) - Most of stations are monitored by the AMMA/CATCH project. The four stations D696, D697, D698 and D699 are monitored by the IMPETUS project. - List of stations for 2001, 2002 and 2003: Station Code Raingage Longitude Latitude Elevation 2001 2001 2002 2002 2003 2003 type Missing Data rainfall Missing Data rainfall Missing Data rainfall °E °N meter % mm % mm % mm Ina-Ceta D601 OEDIPE 2.72347 9.95975 404 8.0 824.0 6.9 1220.7 0,0 1166.5 Fo-Bouré D602 OEDIPE 2.39941 10.1156 425 16.0 923.5 2.8 913.4 0,0 1230.0 Tobré D603 OEDIPE 2.13355 10.1991 371 8.0 1001.4 8.4 441.2 0,0 1329.5 Bori D604 OEDIPE 2.44361 9.74566 353 8.5 1055.0 8.9 1095.5 19,2 1024.7 Gori-Bouyérou D605 OEDIPE 2.55025 9.75497 353 8.4 990.5 2.7 1074.5 15,9 806.0 Sonoumon D606 OEDIPE 2.27383 9.76913 406 13.7 1053.7 Bari D607 OEDIPE 1.96008 9.95569 411 12.2 945.8 Tébou D608 OEDIPE 1.86063 9.95327 383 13.3 1190.8 3.6 1088.5 0,0 1352.0 Affon D609 OEDIPE 2.09402 9.74838 334 74.0 213.5 13.1 938.5 0,0 1375.2 Bonazuro D610 OEDIPE_P91 2.33419 9.45836 386 96.1 0.5 76.1 131.0 13,6 1290.0 Donga D611 OEDIPE 1.9485 9.71097 349 16.4 708.0 3.7 1145.2 6,2 1316.5 Wéwé D612 OEDIPE 2.11608 9.38475 318 12.8 881.0 3.8 1492.8 0,0 1435.0 Momongou D613 OEDIPE 1.85972 9.54655 406 12.1 715.5 3.6 1120.2 0,0 1260.0 Adiangdia D614 OEDIPE 1.984 9.42275 652 87.5 6.2 46.8 651.5 0,0 1295.5 Koko D615 OEDIPE 2.35991 9.06697 312 8.8 949.9 3.6 1086.9 6,4 1028.0 Kopargo D616 OEDIPE_P91 1.55277 9.82983 532 12.1 677.5 7.1 1101.5 15,6 1298.5 Djougou D617 OEDIPE_P91 1.66163 9.692 454 12.3 934.0 6.8 1058.5 31,1 1093.5 Sakouna D618 OTT250 1.88811 9.35786 426 0.0 1335.4 0,0 1230.0 Pélébina D619 OEDIPE 1.63794 9.47352 463 12.3 1111.4 3.6 1136.1 0,1 1375.8 Angaradébou D620 OEDIPE 1.82211 9.22811 377 17.0 972.4 Dogué D621 OEDIPE 1.93783 9.10102 353 8.9 1092.1 3.1 1340.6 17,9 1060.5 Sarmanga D622 OEDIPE 1.77377 9.21727 410 12.3 965.5 2.9 1350.7 0,1 1414.5 Goubono D623 OTT250 1.73261 9.06975 637 5.6 803.0 12.7 1026.0 41,2 873.9 Pénéssoulou D624 OTT250 1.55247 9.2355 419 5.8 726.6 9.3 1333.0 27,3 1473.5 Zoumboubani D625 OEDIPE_P91 1.95283 9.67255 362 20.9 651.2 4.7 986.1 0,0 1196.5 Dapéréfoungou D626 OEDIPE_P91 1.92658 9.73869 366 14.2 853.5 13.6 470.5 27,2 1000.5 Ananinga D627 OEDIPE 1.90941 9.71677 378 14.9 702.0 1.3 837.5 14,0 983.5 Bombone D628 OEDIPE_P91 1.90925 9.68869 382 4.3 1045.7 12.7 1012.5 24,5 1071.5 Gaounga D629 OEDIPE 1.94808 9.74975 370 14.9 1233.5 3.7 965.0 14,8 897.5 Akékérou D630 OEDIPE 1.98488 9.72597 377 17.8 988.5 6.0 938.8 0,1 1366.0 Adiangdia-Ouest D632 OEDIPE 1.97663 9.42625 456 12.9 1172.5 22.7 985.5 12,2 1045.5 Birni D633 OEDIPE_P91 1.53002 9.98988 459 18.5 969.5 7.3 883.0 6,1 1265.5 Bembéréké D634 OEDIPE 2.67355 10.2355 420 8.0 871.0 7.6 1022.0 0,0 1105.0 Biro D635 OEDIPE 2.94386 9.902 453 7.1 678.0 8.0 1146.0 18,4 1116.5 Parakou D636 OEDIPE 2.61261 9.35744 427 12.7 640.5 3.3 957.5 0,0 1176.0 INA-nouveau D637 OTT250 2.72347 9.95975 404 8.4 1077.0 Bétérou D638 OEDIPE 2.27536 9.20194 287 15.0 688.0 5.8 1242.4 0,0 1192.5 Kolokondé D639 OEDIPE 1.78013 9.89266 440 16.6 1208.5 3.8 1082.0 0,0 1574.5 Babayaka D640 OEDIPE 1.56308 9.74788 524 11.7 853.5 0,0 1579.1 Banikani D641 OTT1000 1.64488 9.83438 472 11.1 1096.3 0,0 1640.0 Barienou D642 OTT250 1.77486 9.71169 437 2.9 1280.0 66,7 592.5 Gangamou D643 OTT1000 1.85122 9.84725 419 2.9 704.0 0,0 1162.5 Gountia D644 OTT1000 1.82275 9.77952 415 2.5 1160.3 0,0 1278.0 Koko-sika D645 OTT250 1.92538 9.77372 373 11.4 1057.0 0,0 1369.0 Nalohou_1 D646 OTT250 1.60405 9.74047 473 12.7 1033.5 0,0 1746.5 Parakou_2 D647 OTT250 2.61261 9.35744 427 12.7 1278.5 9,6 1194.5 Noumane D648 OEDIPE 1.69986 9.78072 440 12.7 1036.0 0,0 1541.8 Oualmora D649 OTT1000 1.75172 9.84694 435 3.6 1104.5 0,0 1534.0 Djougou_2 D650 OTT250 1.66163 9.692 454 11.4 1149.3 5,9 1820.5 Nalohou_2 D651 OEDIPE 1.59969 9.75905 499 12.4 982.8 0,0 1561.0 Kpegounou D652 OEDIPE_P91 1.78386 9.80836 401 10,9 1617.4 Dogué(IMPETUS) D696 OTT1000 1.92339 9.09278 ? 0,0 1257.8 Adjimon(IMPETUS) D697 OTT1000 2.02944 9.13092 ? 75,1 382.3 Kpawa(IMPETUS) D698 OTT1000 2.05497 9.15517 ? 7,3 1086.2 Bassila(IMPETUS) D699 OTT1000 1.67142 9.00778 ? 0,0 1641.5 The raingauge data : -------------------- The original data are either 0,5mm increment for OEDIPE rain gauge or 1 minute time step for OTT rain gauge. These data have been converted to 1 hour time step for the years 2001 and 2002 for the CEOP data base. The data covers the rainy season from march to october. The data are in ASCII format. Each line contains: - the day, - the hour (in UTC/GMT time, i.e. local time + 1 hour), - the amount of rain in mm. - Missing data are flagged with the value -999.0. Each file name refers to one station and one year from 1 march to 31 october (i.e. D634_01.1h means station D634 for the year 2001 at 1 hour time step). The data consistency has been globaly checked with operational rainfall data from the National Meteorological Center (Direction de la Meteorologie Nationale, Cotonou, Benin). A more detailled error detection analysis has also been caried out by crosschecking station values at each rainfall event time step for the entire network.
